Okay, I think I get the premise now. I tried this with Seth Rogen.
Dale Denton is a lovable, carefree, pot smoking 20-something guy (Pineapple Express). While on the run from the cops in that film, Dale, in a marijuana-fueled dream, imagines himself as Frank, your average packaged hot dog wiener at the local grocery store (Sausage Party). After waking up and narrowly escaping death at the hands of Ted Jones, his crew, and the Asians, Dale eventually moves to a new city where he forges a new identity for himself but struggles to pay the bills, and under his new alias attempts to make a porno to sell to pay the bills (Zack and Miri Make A Porno).
A few years go by and Dale Denton (now Zack Michaels) is once again single, and moves out to California, where he has cleaned up his life and become a police officer - or so it seems. He takes a high school kid out on the town (Superbad), and when his superiors find out, he is fired. Zack, unable to bear the shame, once again changes his name to Mac Radner.
Mac finally settles down and marries a nice woman and has a kid out in California (Neighbors). However, Mac (Zack (Dale)) gets comfortable and eventually relapses into a destructive pot smoking habit. After a few years he is divorced, changes his name a fourth time to Seth Rogen (thus complicating his life even further, but due to constantly being high, he simply does not give a $&*#) and becomes single. With all of the film revenue he has somehow been making, he once again lives alone, smokes a lot of pot, and eventually dies in the apocalypse and gets to heaven to dance with N*Sync (This Is The End).
