* BoxOfficeBomb: Ultimately, the public listened to Cosby's cries to stay away from this movie; Budget, $24 million. Box office, $4,615,255.
* CreatorBacklash / OldShame: Creator/BillCosby might have co-produced and co-wrote this film, but he ended up begging audiences not to see it shortly before its release. When the film won a UsefulNotes/GoldenRaspberryAward, Cosby asked the studio make his statuette out of gold and marble so he could accept it in style.
* CreatorKiller: ''Leonard Part 6'' was one of the handful of movies that led to distributor Columbia winding up in Sony's hands by 1991, though the damage this film did was more reputation-oriented.
* StarDerailingRole: For Bill Cosby. Any cache he still had as the star of ''Series/TheCosbyShow'' was wiped out by the next film, ''Film/GhostDad'', but he would remain on the A-list for several decades before the multiple rape charges in the mid New 10's ensured both movies would no longer be the bottom of Cosby's career or reputation.
* This movie won a lot of [[UsefulNotes/GoldenRaspberryAward Razzies]], one of which was for Worst Picture of 1987.
