Myers also plays Fat Bastard for the second time, this time parodying the kind of "wire fight" seen in Crouching Tiger, Hidden Dragon. The film also stars Beyoncé Knowles as Foxxy Cleopatra (parodying blaxploitation heroines, primarily Foxy Brown and Cleopatra Jones, as well as Christie Love when she says, "You're under arrest, sugah!" ). Michael York, reprising the role of Basil Exposition, and Verne Troyer in his second appearance as Mini-Me. The film also introduced a new character named Number 3 (a.k.a. the Mole), who is portrayed by former child star Fred Savage. Clint Howard plays a radar operator in all three films. Michael Caine guest stars as Austin's father, Nigel. This role was inspired by The Ipcress File, a 1965 film starring Caine.
