To say the least, "Junior" proposes a VERY original and hilarious concept, and that is of a man being literally pregnant. Dr. Larry Arbogast (Danny DeVito) talks Dr. Alex Hesse (Arnold Schwarzenegger) into going through a secret experiment in which he will be injected with something that will make him pregnant, even though he's a man. However, things go haywire when Dr. Hesse actually decides to go all the way with actually having the baby.
I don't know about everybody else, but the concept of a man having a baby in itself was beyond hilarious to me at first. Since Danny DeVito is one of the main stars, I knew the movie had a great chance of being an effective comedy. To say the least, "Junior" IS hilarious. When you see Arnold Scwarzenegger pregnant and performing some of the antics such as pretending to be a woman and trying to hide the fact that he's pregnant, if you have a sense of humor, then I guarantee that you will bust out laughing!
If you like comedy movies, especially ones that are entirely original, you've gotta at least rent "Junior." But I recommend for all comedy fans to purchase the movie because it's more than worth it!! NOTE: That was my Amazon review from the year 2001. I don't remember it as fondly now, but still funny.
