What do Daniel Stern and Joan Cusack have in common? Canceled TV sitcoms. Stern had “Danny” on CBS, axed earlier in the week as the first casualty of the new season. Cusack had “What About Joan,” the second casualty, and the first for ABC this season. The removal of her show, which began as a midseason replacement last season, actually signals a complete overhaul of ABC’s Tuesday night lineup. “Joan” will eventually be replaced by the hit “Spin City.” “The reality is, Joan Cusack is an enormous talent and a wonderful person,” said ABC spokesman Kevin Brockman. “We have chased her for years. But sooner or later you can’t look at the show like it’s in a vacuum. The impact that show was having was affecting the entire night.” In two other moves, ABC eased the pressure on the highly scrutinized sitcom “Bob Patterson,” starring “Seinfeld” alumnus Jason Alexander. It is being removed from its current Tuesday timeslot opposite NBC powerhouse “Frasier” to a more benign spot on Wednesdays at 9:30 p.m. “Patterson,” the second show to star a “Seinfeld” alumnus (Michael Richards tanked last year), got off to a rocky start and had several roles recast before premiering to lukewarm reviews. ABC is also considering pulling its reality series “The Mole II” from Friday nights, after a disappointing start for the second round of the reality show. Over at Fox, the drama “Pasadena,” like the Southern California city on the San Andreas Fault for which the show is named, is on shaky ground.
