Lea Thompson took home prosthetic breasts from set of 'Back To The Future Part II'

Lea Thompson has revealed that she took home a pair of prosthetic breasts from the set of 1989’s Back To The Future Part II.

The actress, 59, told People magazine that she had a good reason for taking the props home.

During a discussion about the Back To The Future trilogy to mark the the 35th anniversary of the original film’s release, Thompson said: “I didn't want [them] to fall into the wrong hands, because it's actually a cast of my actual breasts inside.

“So I was like, 'I'll take those, thank you very much.’”

Unfortunately, she no longer owns her unique piece of movie memorabilia, as she had to throw the prosthetics away after “they got really smelly because they were latex”.

Thompson was required to wear the prosthetic breasts in Back To The Future Part II because in an alternate timeline her character has implants after her marriage to the villainous Biff Tannen.

The actress also said that she believes the trilogy’s enduring popularity is down to how the films managed to appeal to audiences of all ages because there are “so many levels”.

Thompson also noted that the Back To The Future films are the “perfect storm” of nostalgia, too, as the first film was “nostalgic about the ‘50s,” and now audiences look at the films and get nostalgic about the 1980s.
