Wow! WHAT A COINCIDENCE!
All of the actors listed above have one thing in common - they're Jewish (except for Cera). I tell you, those are some lonnnnnng odds. I mean since Jews make up less than 2% of the population and all. Jews must be just that much more talented, seeing as they seem to land starring roles at a rate that easily exceeds 10 times their proportional population.
Because he's an ugly bird faced man who's wimpy personality and acting only fit the teenage roles. No one wants to see an adult man act like a giant puss.
shareHe still has a career. But he had a period between 2007 to 2010, where he was at his most bankable. It's pretty much where you find all his best work.
Superbad (2007)
Juno (2007)
Nick and Norah's infinite Playlist (2008)
Year One (2009)
Paper Heart (2009)
Youth in Revolt (2009)
Scott Pilgrim vs The World (2010)
That time is probably his most creatively productive and most widely seen work. Superbad and Scott Pilgrim are great. Juno is consider great by many, I think it's overrated. Nick and Norah and Youth In Revolt I think are ton of fun. Paper Heart, I enjoyed it but depends on how you feel about Charlyne Yi. Year one is the only one I dislike from that run.
After 2010, he just seems to have ended up doing more indie work that people barely saw. The only work he did that would be noticeable would be This is The End, Arrested Development, Wet Hot American Summer, Twin Peaks and Voice over for Batman lego movie and Sausage Factory. It just seems to me, he seems happy to do his own thing. He's still only 30, still enough time to pick up big roles again.
