Arnold Schwarzenegger gets pregnant in his 1994 film, Junior.
In this movie, Schwarzenegger played the role of Dr. Alex Hesse who works on a fertility research project together with his OB/GYN colleague Dr. Larry Arbogast (played by Danny DeVito).
They have invented a fertility drug called "Expectane" that is supposed to reduce the chances of a woman's body rejecting an embryo and thus prevent a miscarriage
When their research funding is withdrawn, and human experimentation is denied to them, they decide to test the drug by impregnating Hesse.
