Cats is set to be the latest musical gaining the movie treatment, with the beloved theatre show set to be debuting on the silver screen later this year, and there is plenty of anticipation ahead of its release, with a star-studded cast taking on the roles of the feline favorites.

With several major names having roles in the film, there are plenty of question marks about how the actors will perform in a musical role, with singing and dancing being something that doesn't come naturally to everybody.

Over the years there have been plenty of top actors take on movie musical performances and while some have been career-defining, others have been embarrassing, and within this list, we shall take a look at the five best movie musical performances, as well as five worth forgetting.

Best: Julie Andrews (Mary Poppins)

Mary Poppins is one of the most beloved characters in the history of cinema, and the main reason for that is the fantastic performance that Julie Andrews puts in during this classic, bringing a huge amount of charm and heart to the role.

While the performance seems effortless throughout the film, it could quite easily have gone the other way if she went over the top with everything. Instead, she knows exactly when to go too far and when to pull it back, creating some of the most iconic songs in history

The role of Mary Poppins has produced two fantastic performances in history now following Emily Blunt's excellent portrayal in Marry Poppins Returns, which was made even more impressive by the fact she had to contend with the pressure of living up to Andrews' performance.

Worst: Tom Cruise (Rock Of Ages)

It is fair to say that Tom Cruise would have been better sticking to the action films and hanging on to the sides of planes, as singing isn't really something that he excels in, as the world found out in Rock Of Ages.

This movie musical is littered with bad performances, with Alec Baldwin's singing also deserving a spot on this list, but because Cruise was the lead star people went in expecting him to be a lot better at singing, due to that being the role of the film.

While he brings plenty of star power to the movie as a major A-Lister, the fact he simply cannot sing made this strange casting overall, as he didn't suit the role at all.

Best: Ewan McGregor (Moulin Rouge)

Another fantastic movie musical performance is by Ewan McGregor, who showed his incredible voice during his performance in Moulin Rouge, which remains one of the greatest movie musicals of all time.

Showing just how talented he was as an actor as well as a singer, McGregor produced a performance nobody expected and is one of the main reasons why the film was so incredibly successful. His on-screen relationship with Nicole Kidman really works and is one that most fans talk highly about.

Worst: Russell Crowe (Les Miserables)

Russell Crowe gets an A for effort in his performance as Javert in the movie version of Les Miserables, as he does commit to his performance which is certainly out of his comfort zone, but sadly, it has to be an F for the overall execution.

In a movie that has every word of the film be sung, you really need to at least be able to sing to be part of it, and while Crowe's singing won't make you want to rip your ears off, it also won't have you wanting to have a repeat listen.

Javert is such an important part in the story that it is very noticeable as he has to sing some of the toughest songs, which usually earn a standing ovation in the theatre, making this a tough role for anyone.

Best: Tim Curry (The Rocky Horror Picture Show)

The Rocky Horror Picture Show is one of the most popular movie musicals, with this bizarre storyline having grown a dedicated audience over the years, and a large part of that is down to the brilliant performance of Tim Curry in the film.

His performance has become iconic, as Curry dives headfirst into the role, taking on the challenge of making the character seductive, yet creepy, all the while entertaining.

The character has become a huge fan favorite within the movie and the Broadway performance, with Curry being the first person people think of when it comes to the film, with this performance being simply outstanding.

Worst: Michael Caine (The Muppet Christmas Carol)

When The Muppets took on the Christmas Carol story there were many different ways they could have taken it, but it was decided that they would put on a musical version that would star Michael Caine in the lead role of Scrooge.

While getting Caine to star in the movie was a great idea, having him sing was not. While the experienced actor certainly gives it his best shot, this is clearly not an area of great comfort for him as he goes through the musical numbers.

Caine sounds exactly as you might imagine, keeping up his classic cockney appearances here as he sings/talks his way through his lines, making this a musical that would have been improved from keeping Caine to a talking role only.

Best: Lady Gaga (A Star Is Born)

While this is a much more serious and dramatic movie than many on the list, at its core A Star Is Born is very much a musical, with the songs being at the core of the movie as the driving force that takes the plotline from point A to point B.

From start to finish audiences are gripped throughout and it was worthy of all the plaudits it got, and while everyone knows Lady Gaga is a fantastic singer, this performance is much more than her just belting out a few tunes.

Gaga brings a level of emotion to the performance that is simply breathtaking, with the on-screen chemistry between her and Cooper carrying this movie to great heights.

Worst: Clint Eastwood (Paint Your Wagon)

Paint Your Wagon Cropped

You know you've had a bad performance when The Simpsons mock you during an episode, and that is something that Clint Eastwood suffered from his performance in Paint Your Wagon.

Eastwood might be one of the all-time greats, but his performance in Paint Your Wagon isn't a contributor to that, with this three-hour musical being one that very few enjoyed due to the fact that the majority of the stars cannot sing.

Eastwood is one of those actors, and the fact that nobody can seemingly hold a tune in this movie makes it one that most people struggle to really invest into, despite the star names attached to it.

Best: Hugh Jackman (Les Miserables)

There was a real pressure from a large and dedicated fan base for the actors involved to get this spot on and for the most part, that is exactly what they did, especially Hugh Jackman.

Playing Jean Valjean, which is the lead role within the story, Jackman really got to show his range due to how much Valjean ages throughout, doing an excellent job with both the singing and the emotional aspect that the role demands.

Jackman also put in a stellar performance in The Greatest Showman, which was so good he helped create one of the most popular movie musicals in modern cinema, despite the fact it was a totally original story.

Worst: Pierce Brosnan (Mamma Mia!)

Pierce Brosnan might be one of the greatest actors to ever portray James Bond, but his performance in Mamma Mia! being one that most people would like to forget. Put simply, Brosnan isn't a very good singer.

Thankfully, because Mamma Mia! is such a fun movie that is jam-packed with uplifting and upbeat songs, Brosnan's performance manages to skate through and not destroy the film, which proved to be a giant success that even warranted a sequel.
