Leonard Part 6 is a 1987 comedy film starring Bill Cosby — and a film that was so notoriously bad that the star himself told people not to see it. In his defense, Cosby was contractually obligated to promote the movie; said contract didn't specify how he could promote the movie, and so Cosby was abiding by his full legal rights when he appeared on every late night talk show warning people to stay away.
The story is ostensibly the sixth great adventure of top CIA agent Leonard Parker (Cosby), the others remaining classified for now. Leonard has gained a wide variety of eccentric skills over the years, and now that he has been brought out of retirement, to stop a plot by evil vegetarians who plan to train animals to kill people, he will have to use most all of them to save the day... and his relationships with his ex-wife and daughter, while he is at it.
There is no Leonard Part 1 through 5, if you were wondering; the title itself is a spoof of multi-part spy thrillers. And even if there were prequels, Cosby would have probably destroyed them all by now. Or traded them in for a lifetime supply of pudding and JELL-O.
- Aborted Arc: The MayDecember Romance between Joan and Giorgio never gets resolved.
- Animal Assassin: The evil vegetarians plan to train animals to kill people.
- Animated Credits Opening: The credits are accompanied by crude animations out of animal drawings.
- Award-Bait Song: "Without You", performed by Peabo Bryson (a few years before he became one of the go-to guys for this trope) and Regina Belle. It was actually a radio hit and was succeeded five years later by them reuniting to do "A Whole New World" together of course.
- Body Double: Fairly obvious when Leonard has to dance. The reason for the weird helmet was to ensure no one would notice it wasn't Cosby.
- Chekhov's Armory: A psychic gives Leonard an arsenal of Deus ex Machina items such as melted butter (to scare killer lobsters.)
- Cool Car: Leonard's armored, camo-colored, tank-turreted Porsche.
- Dance Battler: Leonard's ballet lessons when he was undercover with the Bolshoi ballet helps him when he fights Medusa's minions.
- Deus ex Machina: The seer gives Leonard a bunch of Deus Ex Machina devices. Their purpose is unknown til the time to use them comes.
- Evil Is Hammy: Medusa is entertainingly over-the-top.
- Evil Vegetarian: Medusa, who leads a whole group of evil vegetarians to kill people with animals.
- Food Slap: Leonard ends up wearing most of the meal when he dines with his estranged wife - both times.
- Fruit of the Loon: The film made a point of depicting the vegetarian villain look extra-crazy by having her always eating fruit while she ordered around her mooks and pursuing her wacky plans. Mind you, this is a food-obsessed movie anyway.Medusa: Grape me!!
- Idiot Hero: play for laughs, Leonard has also made some dumb choices, one of them is when he and his Butler decidde to replace the Liquid inside the Sphere with Dish Washing Soap, only to discovered later, it does work with Dish Wash.
- Indestructibility Montage: One sequence has Leonard trying and miserably failing to blow down a door with a series of gadgets and weapons on his elaborate battle suit.
- Kitchen Chase: Monroe is shooting at Leonard with a revolver, switches to an uzi, then switches to another revolver, and his shooting "accidentally" opens a bag of coffee beans into a coffee grinder, breaks a couple eggs for frying, and punctures a carton of oil which some eager chefs help themselves to for cooking.
- Notice This: It's hard not to notice when an item of the Chekhov's Armory ends up being used because most (if not all) of them are surrounded by a glitter effect when Leonard pulls them out.
- Offscreen Moment of Awesome: Invoked In-Universe during the intro by Leonard's butler, who said Parts 1 through 5 were so awesome they had to be classified. Take their word for it.
- Overt Operative: Leonard is supposed to be a secret agent, right? Highlighted by him tooling around in a car with a tank turrent on it.
- Product Placement: One scene contains a refrigerator full of Coca-Cola cans (Columbia Pictures' owner at the time), whose labels are all conveniently facing the camera. Elsewhere, a table with a huge stack of Lava Soap bars upon it appears backstage at a theater, and Alka-Seltzer proves vital to the climax. Roger Ebert went into a rant about this while reviewing the film on Siskel & Ebert; see Berserk Button on the series' page for the full quote.
- Retroactive Legacy: Supposedly the sixth in a series featuring the eponymous character.
- Road Trip Across the Street: The "agonizing ride" for Leonard to see his estranged wife.
- Self-Surgery: Played for laughs as Bill Cosby's character removes a bullet from his own shoulder.
- Take That!: The character of Leonard's daughter is widely seen as an attack on Lisa Bonet and her role in Angel Heart, especially the theater scene in which she removes her clothes for no real reason.
- Un-Installment: We never did see Parts 1 through 5... because they were locked up "in the interests of world security".
- Unusual Weapon Mounting: Leonard has weapons on his battle suit mounted on the weirdest of places, perhaps the most ridiculous being his underarm rockets.
- Unusually Uninteresting Sight: The chefs from Leonard's restaurant don't think much of a hitman attempting to murder their boss....
- We Have to Get the Bullet Out!: Leonard, having been shot, removes the bullets himself, his trusty manservant only standing by with surgical tools and a mirror. Given the large jar full of bullets that the extracted slug ends up in, this is not the first time he's had to do this by a long shot.
- Weaksauce Weakness: Medusa and her minions are such hard-core vegetarians that waving sausages and hamburger patties at them acts like a vampire seeing a cross. Then again, the one goon that is brave enough to take a bite out of Leonard's sausage has the ultimate violent reaction — his head explodes.
- Weaponized Animal: Among the animals trained by the evil vegetarians to kill people is an ostrich with missile launchers mounted on it.
- Weaponized Car: Leonard's spy car has a cannon turret on its hood.
- Your Head Asplode: This happens to one of Medusa's mooks in the climax, as the unexpected-by-anyone result of Leonard forcing him to taste meat.
