I don't know if you are being sarcastic or not, but the kid in zombieland is poor-mans Michael cera, not michael cera.
micheal cera isn't in zombieland ha but that movie does look funny hes not the poor mans micheal cera, hes the kid from adventure land,cursed,the emperors club etc. his name is jesse Eisenberg
and sound the exact same. Maybe they are clones, or have the same father, just different mothers. Maybe they are both sperm bank babies and their mothers got it from the same guy.
Jesse Eisenberg and Michael Cera can be switched around. They are typecasted into the same roles. I think Cera plays the stupid/dumb/innocent role much better. I think Jesse can play more mature roles than Cera though.
