Charlie Hunnam was offered a role in Forgetting Sarah Marshall
Latest Men's Health has a feature on Charlie Hunnam. Apparently he was offered the role of Aldous Snow (Russell Brand's character) in Forgetting Sarah Marshall (Jason Segel wrote the role with him in mind actually) that starred Jason Segel.
I do think Brand is the better choice, but it would have been awesome for another mini Undeclared reunion. It does give me a bit of hope that maybe one day he'll be in an Apatow flick again~
He also didn't give himself enough credit about comedy (another reason why he turned the role down). I thought he was great in Undeclared.
