Cartoon dragons and a time-traveling comedy hit the silver screen this week

(NBC) - If you're up for a laugh, there are a couple of new movies to tickle your funny bone in theaters this week.

In "She's Out Of My League" actor Jay Baruchel finds his cartoon self overmatched in "How To Train Your Dragon."

Baruchel plays Hiccup, a teenage viking out to prove his worth as a dragon slayer on his small island.

But his encounter with an injured dragon turns his world upside down.

This one's from the studio that brought you Shrek and Kung Fu Panda.

"How To Train Your Dragon" is rated PG.

Four buddies party-hardy in a ski resort hot tub only to wake up in 1986 in "Hot Tub Time Machine."

After coming to terms with their time-travel predicament, John Cusack and friends all decide to try to alter that past to try to prevent the dismal future which led them to the guys-only hot tub party in the first place.

"Hot Tub Time Machine" is rated R.

Opening in limited release this week is the infidelity drama "Chloe."

Amanda Seyfried is a call girl hired by Julianne Moore to catch her husband in the act.

That husband is played by Liam Neeson, who suffered an off-screen loss while filming this role, the death of his wife Natashsha Richardson.

Another limited release is the coming-of-middle-age dramedy "Greenberg."

Ben Stiller is in full misfit mode as a New Yorker in la, an out-of-work musician house-sitting for his successful brother, all while coming to grips with being single in his 40s.
