Considered by many to be his best film, writer/director/star Jerry Lewis' slapstick spin on the Jekyll/Hyde story finds him, as nerdy college professor Julius Kelp, inventing a mysterious potion that turns him into hip, conceited stud Buddy Love (whose persona, some say, was based on Dean Martin). Stella Stevens plays his love interest, Miss Purdy. With Del Moore, Kathleen Freeman. 107 min. Widescreen; Soundtracks: English DTS HD 5.1 Master Audo, Dolby Diigital mono, French Dolby Digital mono, Spanish Dolby Digital mono; Subtitles: English (SDH), French, Spanish; audio commentary by Lewis; featurettes; deleted scenes; bloopers; more.
