Tommy Boy

After Tommy (Chris Farley) barely graduates from college, he returns home to the Midwest where his father (Brian Dennehy), the owner of an auto parts factory, immediately employs his dumber-than-dumb son. While Tommy was away at school, his father had fallen in love with a beautiful woman (Bo Derek) and now desires to marry her. During the wedding ceremony, however, Tommy's dad tragically dies from a heart attack, which puts the company's--and its 300 employees'--future at stake. It is up to Tommy to use any available intelligence to keep his father's factory from going under. (official distributor synopsis)
