Can't remember the last time I heard such full and real laughter in a movie theater. There were shrieks and howls during the sneak preview of Andy Samberg's new film, Hot Rod, tonight at Towson Commons. The gags and pranks were juvenile and goofy and random and completely cracked -- just the way you've got have it once in a while.

This is Napolean Dynamite meets Talladega Nights. Samberg plays a really bad stuntman in a JOFA helmet, attempting Evil Kneviel jumps on a moped, and he's trying to be a mensch and save a life, too.

Favorite line? I'd have to see Hot Rod a couple more times to make up my mind. Right now, the front runner is: "Never sneak up on a man who's been in a chemical fire."

Sissy Spacek plays Rod's mom. Rod's pit crew is motley, a bunch of NapDynamite-like misfits who win the day. Ebeneezer Scrooge shows up on a school bus with a goose. There's an amusing rip on the long, slow death of AM Radio, too.

Isla Fisher is a doll. Samberg is one of the best punch dancers you'll ever see.
