CBS won’t pick up the comedy "Mad Love" after actress Lizzy Caplan couldn’t commit to a series, Nellie Andreeva reports at Deadline.com. 

Caplan has movie commitments and is also on Starz’s "Party Down", and had agreed to act in the pilot "as a favor" in a guest-starring capacity. "Problem is, she played a lead and everyone, especially at the network, really liked her. Attempts ensued to persuade Caplan to stay on as a regular, but no-go — so now the project is a no-go for the moment. I hear it could remain in midseason consideration, and a new pilot might be shot in the summer," Andreeva writes.

As for two other dramas in contention, "Chaos" and an untitled medical drama from John Wells, "both seem still alive." CBS holds its upfront presentation today.
