Woody Allen recorded his part as "Z" in only five days.
The song the ants are dancing to in the bar is "Guantanamera".
The sound effect accompanying the magnifying glass is the alien saucer sound from The War of the Worlds (1953).
One of the motivational signs in the ant colony, "Free Time Is For Training", is a real motivational sign at PDI.
The dance Z and Princess Bala do that seems to be inspired by Pulp Fiction (1994) is actually a reference to the Batusi, the dance by Batman from the TV show "Batman" (1966).
Z's line "I was going to include you in my erotic fantasies" was originally "I was going to include you in my most erotic sexual fantasies", but was shortened to retain a PG rating. In the German dubbed version the "sexual" is included. The line was from a spider sketch called "What Causes Homosexuality?" which was cut from Allen's Everything You Always Wanted to Know About Sex * But Were Afraid to Ask (1972). Woody Allen was going to use that line as Louise Lasser was about to eat him - the sketch was never used because Allen couldn't think of a way to end the scene. Since the sketch was not used, the writers got a hold of the line and, realizing the irony (spiders, ants), had Allen's character (Z) state it.
Woody Allen was offered accompaniment to sing "Almost Like Being In Love", but he refused, preferring to sing it a capella, and did so.
Arnold Schwarzenegger was originally offered the part of Weaver. When Schwarzenegger wanted to be paid for the role, it went to Sylvester Stallone who was willing to do it for free.
