City Slickers (1991) is a great adventure comedy starring Billy Crystal, Daniel Stern, Bruno Kirby, Helen Slater and Jack Palance.
The plot revolves around mid-life crisis plagued Mitch Robbins (Crystal) and his two friends (Kirby/Stern) who go on vacation driving cattle across country.
Billy Crystal is very funny in this movie. His character is very sarcastic and Crystal excels with his fast wit and dry delivery. Kirby and Stern are good value in supporting roles but its Jack Palance who steals the show as cowboy boss Curly. Palance won a Best Supporting Actor Oscar for his tough but funny performance.
Director Ron Underwood (Tremors) does a great job mixing the action, comedy and some pretty deep character building moments. City Slickers is a very funny movie with plenty of excitement and drama. It's very highly recommended. Stay away from the sequel though.
