From IMDB:

A magic potion returns artist Vincent Van Gogh back to life and lands him in the center of the Rose Bowl Parade in this oddball comedy. Of course, no one believes who he is and he is startled to discover his popularity after the passage of time. This sets him off on a crusade to steal his paintings back from collectors and sets a detective on his trail. Along the way, he makes friends with an ambulance chasing attorney and a young artist, who gradually begin to believe his claims of identity.
