Am I the only one?

You're not alone Callistio, the similarities are UNCANNY. He is like a thinner more handsome Seth Rogen. I'd like to see them play "non-identical" twins (Mary-Kate and Ashley Olsen) with very different personality traits.

Just watching Delivery Man now and I seriously thought he was Seth's real life better looking younger brother. I can't believe he's not. You're not alone.

I thought I was the only one that tought he looked like Seth. Even the way he speaks like the way he moves his lips is like Seth's.

I actually thought he looked like Chris Pratt. I guess that's because there was a trailer for Guardians of the Galaxy before the movie. But now that you mention it, yes he does look like Seth Rogen.

I thought Chris Pratt also. I actually didn't even think of Seth Rogen, I still don't see it.

Just saw Delivery Man and I was telling my mate that he should be playing Chris Pratt's son not Vince Vaughn's !

yes, even in 'Sing Street' in one scene - he looked A LOT like Chris more so than Seth.

Many he/she looks like I can't see but even his profile picture. . . Seth Rogen's better looking cousin!
