Bullseye! (1990)

Sir Roger Moore and Sir Michael Caine play dual roles in this off-beat and highly silly caper, a pair of small time conmen, and a partnership of nuclear physicists. As conmen, they use their uncanny resemblance to the high-living scientists to con their way to the scientists' safe deposit boxes, but in doing so, become entangled in a shady world of spies and international intrigue.
