Andrew Bergman has written some dandy private-eye novels, not to mention the script for The In-Laws (the original). So how could you go wrong with So Fine, a movie he wrote and directed? Answer: You can't. Or I couldn't.
Ryan O'Neal is Bobby Fine, an English prof up for tenure. His father, Jack Fine (Jack Warden) is an unsuccessful clothing maker, in deep debt to Big Eddie (Richard Kiel). Through a complicated set of circumstances, Bobby is kidnapped and set up as head of the company. He's also quickly involved with Kiel's beautiful wife, Lira (Mariangela Melato). While fleeing Kiel's bedroom, Bobby accidentally invents So Fine jeans (see poster) and saves the company from financial ruin.
The movie's full of jokes, so many that you might miss one while laughing at another. It has the greatest production of Verdi's Othello ever. It has Richard Kiel lip-synching to "Walk Like a Man." It has O'Neal giving a version of Henry V's St. Crispen Day's speech to the garment workers. Maybe this movie's not as funny as I think it is. You can let me know in the comments.
