The Cannonball Run1981

[during the brawl with the mean bikers, Seymour Goldfarb Jr stands aside with his girlfriend, until one of the bikers menacingly approaches them, holding heavy wrench]

Seymour Goldfarb Jr:
[to his girlfriend] Step back, my dear.

[the girl steps back. Seymour makes karate moves, with the music of James Bond movies is played in the background]

Seymour Goldfarb Jr:
[to the biker] I must warn you, I'm Roger Moore!

Biker:
[frowns] Who?

Seymour Goldfarb Jr:
[bends forward so the biker can hear him better] Roger Moore!

[the biker, unimpressed, punches Seymour in the mouth. Seymour groans in pain, covers his mouth, then helplessly slumps to the ground]
