The Secret Of My Success (1987)
Seen this a few times... is it me, or is the entire movie packed with seriously unlikeable characters?
Fox spends the entire film lying to Howard (his Uncle and boss) and banging Howard's wife Vera, which is technically his Aunt... then Fox sniffs after Slater, who is banging Howard...
Fox, Vera and Slater then all form a hostile takeover and run Howard out of his business.
I'd feel sorry for Howard, except he was also cheating on his wife with Slater.
It's basically a cast of suit stereotypes and cheats, all cheating on each other and lying their way through the film.
Then there's the tone that goes from something akin to a Carry On movie, then changes to a Scooby Doo slapstick doors-in-corridors routine and then becomes something that wants to be Wall Street.
