Why should he get a shot? Because he did an average Hulk movie that had a lot of creative tension between Marvel and Ed Norton?
Leterrier can make a movie that looks decent and pretty, but he doesn't get the feeling and charm and excitement these movies should have.
Clash of the Titans was beyond dull. It proves he's not a true fan of the original nor does he understand what makes the original great. He compares comic book superheroes to Greek Gods, yet his interpretation of the Gods of Olympus was beyond lame. The Gods were all insignificant minor characters in his story.
Wow what a strong opinion. I hope this isn't because of the apparent lack of support for your boy Raimi.

Anyway, I didn't find COTT dull at all. I thought it was rather enjoyable. Yes there was some cheezy stuff in it, but the overall picture is also a function of the writing and not just the directing. And how does the final product show that he is not a true fan of the original? And the story isn't (and never was) focused on the gods. It was a different take on the story. I was fine with the movie. And I have a feeling that most of the backlash results from the bad 3D effects, which will surely bias a reviewer and anyone else. I didn't see it in 3D and again, IMHO, it is better than the majority of the reviews
So, I wouldn't be disappointed at all if they gave Avengers to him. But I have a feeling they will put him as a producer much like Favs.
