Loaded Weapon 1

Taking one step forward and two back, Bruce Willis again made an uncredited appearance in the 1993 National Lampoon crime-comedy Loaded Weapon 1, a spoof of the Lethal Weapon series starring Mel Gibson and Danny Glover. Given that his brother David was a producer on the National Lampoon hoo-ha - and probably because his mother made him - Bruce makes a cameo as John McClane, whose mobile home is destroyed by accident because the villains got the address wrong.
