Another Seinfeld vet is plotting a small screen comeback. According to The Hollywood Reporter, Jason Alexander is attached to star as a dysfunctional motivational speaker in the sitcom Bob Patterson. The actor will produce the project along with 20th Century Fox TV; the studio will begin shopping the show around to the networks in the next few days. Last week, news broke that Alexander's Seinfeld co-star, Julia Louis-Dreyfus, also is planning a return to TV in a comedy written by her hubby Brad Hall. (Let's hope they're both better than The Michael Richards Show.)
