If you put the cast of The Avengers together for a photo shoot, it would provide a great cover for GQ. If you put the cast of The Dark Knight Rises together for a photo shoot, it would include some of the finest actors working today.
There's no arguing with the fact that The Avengers offers up a strong cast - with Robert Downey Jr. as the best of the bunch. But many of the other actors composing the cast are younger performers who haven't established themselves as great actors quite yet - whereas the Christopher Nolan Batman films offer up one of the strongest casts ever in comic book movie.
Four of the main actors in TDKR (Christian Bale, Morgan Freeman, Michael Caine and Marion Cotillard) have all won Oscars for their acting skills. Additionally, the film's supporting cast includes the massively-talented combination of Tom Hardy, Joseph Gordon-Levitt and Oscar-nominees Gary Oldman and Anne Hathaway. This is an incredible cast - not only for a superhero movie, but for a film in general.
