Alba has her opinions on nudity in films. She believes that nudity should only serve as an artistic purpose rather than bring a "shock value" to the production. Alba has maintained her position since 2005, when Elle Magazine asked her the same question. “If you look at the movies I have done, getting naked would never ‘elevate’ the picture,” she added.
Rebel Wilson
Rebel Wilson broke into the acting scene in Bridesmaids and Pitch Perfect. She definitely has a wild side, but that doesn't mean she will go fully nude for a movie. She even has a body double for her nude scenes, who is a South African burlesque dancer.
“I want to know that the people (i.e. the film crew) have a certain sensibility and decency. And a lot of times in comedy, they’re not those people,” Wilson told Marie Claire. Wilson is more interested in showing her fans her comedic skills, not her body.
Anna Kendrick
Even though you thought you saw Anna Kendrick nude in Mike and Dave Need Wedding Dates, you were wrong! Kendrick actually used a body double for that nude scene. She's expressed that she likes avoiding being a "teen movie actress" but that she's still able to keep her clothes on.
