6. Danny DeVito is a DOM.
This established actor plays Al, a sleazy sausage magnate who asks Beth for a private tour of the Guggenheim museum, where she works as a curator. To woo her, her gives her a pack of sausages plastered with his face and the Sausage King logo. Yes, we know how dirty those last two sentences sounded.

7. Will Arnett paints a naked mural.
Will plays Antonio, a painter with a heavy Italian accent and an unhealthy foot fetish. Watch for the part where he drives a yellow clown car through the streets of New York, with his three co-suitors squeezed together in the backseat. The car is so tiny that Al has to ask, "Who makes this? Fisher Price?"

8. Jon Heder is… well, Jon Heder.
Who hasn't heard of Jon Heder? In this movie, he portrays Lance, a street magician desperate for Beth's love. "Street magicians are creepy," Jon says. "I think that's what I liked the most." If you loved him in Just Like Heaven and Blades of Glory, you'll enjoy seeing him try to impress Beth with his card tricks and his own (epic fail) version of The Great Mummy Escape. Bonus: Pedro from Napoleon Dynamite makes a cameo!

9. People get hurt. Literally. A lot.
"There's a lot of chasing involved, a lot running in heels," Kristen says. "I'm very klutzy in real life, so I didn't need training [to be funny in those scenes]." When in Rome is physical comedy at its finest, which means it won't require you to put on your thinking cap just to have a good laugh.

10. Romance isn't taken too seriously.
"I'm not a big traditional romantic comedy guy," says director Mark Steven Johnson. "I wanted to make a comedy with romance, versus a 'romantic comedy.' I wanted to make a comedy that was really funny but also had a big heart." While this movie probably won't give you any grand insights about love and life, it will definitely entertain you. And if you're still not convinced, maybe this tweet from Dax Shepard will work: "Attn Guys Who Like Having Sex At The End Of A Date: Take your lady to When In Rome on Friday. You will secretly love it too."
