There are times when I just need mental popcorn, so If you are looking for a silly movie, this is it. I love this movie - it's got some great lines and Sam Elliott. This amazing cast is a trivia lover's dream: Rebecca from Cheers, Princess Leia, Beckett from Quantum Leap, Al Bundy, Muffy from Square Pegs, the husband from Maude and more. Bill Pullman is a great supporting actor.I want Sam Elliott's voice to make love to me. To this day, there are times I remember that line "It wasn't sex, it was GOOD!"I give it 8 out of 10 stars for it's genre: chick flick romantic comedy.

Hands down, one of the worst movies I've ever seen. The premise was lousy, the script was dull, and the performances were mediocre at best. At no time did I feel like I had been pulled into a believable excerpt from the characters' lives, the way a good movie's story should make the viewer feel. I was always aware that I was watching a group of actors trying to work with some of the worst material in Hollywood history, and not succeeding.On a deeper level, it simply annoyed me. Adultery is not the solution to marital problems; it just makes more problems. Yet to watch this movie, you would think that the best way to combat boredom in your relationship is to have an affair. Then everything will be all right again! It doesn't work that way. Overall, I was profoundly disappointed by the entire thing. I watched it in the dollar theater and I felt like I had been overcharged.

Regardless of the negative comments about this film I think Sibling Rivalry is a brilliant comedy. The all-star cast were fantastic and hilarious in their roles and boy was it really funny and entertaining throughout. This is a really great movie that will keep you laughing although there are some serious drama in between this is an enjoyable film. Scott Bakula is the only reason I watched this film in the first place and I thought he was just brilliant. Scott plays Harry who's from a family of doctors with Carrie Fisher as Iris she plays his sister and Harry's brother is played by Sam Elliot as Charles. Kirsty Alley is beautiful and fantastic as Marjorie she's just married to Harry and happy for a while until she grows bored and frustrated that they never make love. Unhappy and unsatisfied she meets a man in a shopping store this soon leads them both to a hotel room where she spends the night with him. After that what happens is through funny consequences and it's completely funny. The whole cast do a brilliant and are all great fun to watch. I'd give this film a try if your just looking for laughs because I certainly enjoyed this film very much.

This movie reminded me a lot of "Arsenic and Old Lace." I don't really know why. Except for the dead body. I am a big fan the Carl Reiner and his son Rob Reiner.. I believe that their contribution to the America Cinema is incommensurable. Bill Pullman (Zero Effect) does a wonderful job playing really clumsy people. Carrie Fisher (Sleepless in Seattle) is great playing the snobbish pain in the neck sister in law. The script is funny! I ran into this movie by coincidence. One of those on sale type things and I found a great little funny movie. I recommend it!
