Upset over that letter on Tuesday, NBC boss Jeff Zucker is taking a “super tough threatening position†over Conan’s refusal to host a postmidnight Tonight Show and, according to Nikki Finke, he’s threatening to “ice†the host, enforcing a no-compete clause that would keep him off of any rival network “for 3 1/2 years†(the length of his current contract). Even more disappointing than all this acrimony, though, is that Finke did not Photoshop Zucker into a Mr. Freeze costume. [DHD]
