Eugene Levy and Catherine O'Hara play one of the funniest married couples on TV with their portrayals as Johnny and Moira Rose on Schitt’s Creek. The Canadian sitcom, however, isn't the first time the duo has worked together on-screen. Levy and O'Hara have collaborated on a number of projects over the last four decades. 

Levy and O'Hara are both Canadian actors who hit their stride in the industry around the same time. Levy went on to become a profound comedian, writer, and director. He has appeared in dozens of projects within TV and film, but his most notable role would be his portrayal of Noah Levenstein in all eight films in the American Pie franchise. O'Hara, on the other hand, got her start in 1975 working alongside John Candy and Dan Aykroyd in Coming Up Rosie. The successful writer and comedian has also appeared in a slew of projects and is best known for her roles in Beetlejuice, Home Alone, and Temple Grandin.

The collaboration between Levy and O'Hara began in 1976 when they were both cast members of Second City Television. SCTV was a Canadian sketch series that served as an offshoot of Toronto's Second City troupe. Other notable cast members during its run included John Candy, Harold Ramis, Andrea Martin, Rick Moranis, and Martin Short. Following their time on the sketch show, Levy and O'Hara worked on six films together before reuniting for Schitt's Creek in 2015.

Levy and O'Hara frequently worked with screenwriter and director, Christopher Guest. In 1996, they starred in Guest's mockumentary film, Waiting for Guffman. Levy not only starred in the comedy but he also co-wrote the script with Guest. Levy and O'Hara played hopeful amateur performers hoping to land a spot in a community theatre production. The cast in the mockumentary improvised most of the dialogue based on the story created by Guest and Levy.

The trio worked together again in the 2000 mockumentary comedy, Best in Show. This time around, Levy and O'Hara portrayed a married couple who are competing with their pet in a major dog show. The additional projects that they worked together on include Nothing Personal (1980), A Mighty Wind (2003), Over the Hedge (2006), and For Your Consideration (2006).

Less than a decade later, Levy and his son, Daniel Levy, would go on to co-create Schitt's Creek. Due to Levy's past with O'Hara, he instantly thought of her for the role of Moira Rose. Their chemistry as the elder Rose members was a culmination of all of their previous work together. The duo works so well together that many viewers confuse them for an actual married couple. The performances from Levy and O'Hara in Schitt's Creek has finally resulted in Emmy nominations for the both of them. Unfortunately, Schitt's Creek season 6 will also be the show's last. Here's hoping that Levy and O'Hara continue their working relationship in the near future.
