Percy (1970) is a British comedy film directed by Ralph Thomas (1915 - 2001) starring Hywel Bennett, Denholm Elliott, Elke Sommer and Britt Ekland. The film is about a successful penis transplant. An innocent and shy young man (Bennett), whose penis is mutilated in an accident and has to be amputated, wakes up after an operation to find out that it has been replaced by that of a womanizer, which is very large. The rest of the movie is about its new owner following in his predecessor's footsteps and meeting all the women who are able to recognize it.

Rather than for its plot, the film is today remembered for its soundtrack by The Kinks (for example "God's Children").
