Backtrack (1990)

Jodie Foster stars as Anne Benton, an artist who sees what she shouldn't—a mob assassination. The police want her to testify; the mob wants her dead. So she goes on the lam, moves to another state and adopts another identity. But she can't hide from Milo (Dennis Hopper), the mobster sent to kill her.

This is director Dennis Hopper's recut of a theatrical release called "Catchfire," which was disowned by Hopper and credited to Alan Smithee.
