These are fun and should be watched in the opposite order because that's the order the shows were made in. Some of the casting is the same in both movies but oddly, one woman plays a different agent in each and her role in the Melrose Place one didn't make it onto the IMDb entry.
And the casting of Abbie Cobb as Jennie Garth is the most brilliant biopic casting I've ever seen. She looks so much like her I could barely believe it.
