'ER'(10PM, NBC)
Is he or isn't he? That's the not-so-secret secret, as original series star George Clooney is rumored to make a cameo appearance.
What's confirmed: Clooney's fellow former co-stars, Eriq La Salle and Julianna Margulies return just weeks before the April 2 series finale, as La Salle's Peter pops in to visit Noah Wyle's ailing Carter. Margulies is back as Carol Hathaway, and the actress says she only agreed to visit when Clooney agreed to return as Hathaway's love Dr. Doug Ross.
As for what the on-screen lovers might be up to now, it's all very hush-hush, but producer John Wells has hinted that Hathaway-Ross fans will be happy with the storyline.
