The Comeback

For nine years (time passed between the first and second season of the show) Lisa Kudrow and Michael Patrick King often talked about Valerie, both wondering where she'd be.

Michael Patrick King stated to The Writers Guild Foundation in 2012 that none of the actions or dialogs in the show were improvised. He said that the improvisation happened only during the writing process. During their meetings, Lisa improvised dialogs and actions as Valerie while Michael tried to transcript the most of it that he could. For Michael those were the toughest moments and he really thought about hiring a stenographer to do that because everything Lisa did and said during improvisation process was so rich that he was always afraid lose any of it.

The roles of Mickey and Jane were written specifically for Robert Michael Morris and Laura Silverman.
