Attack of the 50 Foot Chihuahuas from Outer Space (1998) was directed by Jaimz Asmundson. Giant malevolent chihuahuas plan to take over the Earth. A witness (Kyle Lemke) tells his psychiatrist (Graham Asmundson), "A giant chihuahua chased me down the street and pissed on me. You're the first person I've told."
The leader of the invaders is played by the filmmaker's chihuahua Jen. In the scene where she pees like a boy-dog, if you look close you can see the string attached to her leg. She was very forbearing during the film shoot, and seemed to enjoy herself.
The three chihuahuas have the ability to transform into hot babes, which lent to this film's re-edit carrying the alternative title Doomsday at Bikini Beach (1999). The director has a cameo as the chihuahua devottee in the psychiatrist's waiting room.
