No one will ever look at a plate of chips and dip the same again. Halle Berry** has gone topless for roles before, but in her latest film, she takes the nudity to a new level when she dunks her breast into a bowl of fresh guacamole.

The raunchy scene is part of the project Movie 43, produced by Peter Farrelly (one half of the Farrelly brothers comedy team). On Wednesday, Jan. 23, the Dumb and Dumber director participated in an "Ask Me Anything" session on Reddit, during which he was asked which actor surprised him most on set.

"I would have to say Halle Berry...I was a little nervous about meeting her because her scene is so outrageous, and I was afraid she might get on the set and balk," Farrelly explained of the Oscar winner, 46, mom to daughter Nahla, 4. "Not only did she not, but she thought the scene was too soft and asked us to amp it up a little."

A little turned into a lot. "We ended up coming up with a couple of things for her to do that weren't scripted but were insane," Farrelly said. "To give you an example, [her scene] is about a couple (her and Stephen Merchant) who play Truth or Dare on a first date. Among other things, she ended up sticking her bare breast into a bowl of guacamole. She couldn't have been more fun to work with."

However, sources told E! News -- and Berry's rep confirmed -- that the breasts you see in the film are prosthetics. "They're so huge," one insider said. "You can totally tell they're fake."

Movie 43, which is being billed as "The Biggest Cast Ever Assembled For the Most Outrageous Comedy Ever Made," is a series of interrelated shorts shot by Farrelly and 11 other directors. Among its star-studded ensemble? Kate Winslet, Hugh Jackman, Emma Stone, Anna Faris, Naomi Watts, Gerard Butler, Richard Gere, Uma Thurman, and Liev Schreiber.
