Bryan Cranston to '30 Rock'?

Bryan Cranston hopes once again to kill in the benevolent sense of the word. According to TV Guide, he'll play a father figure to Kenneth Parcell, Jack McBrayer's lovable hillbilly, on the upcoming seventh and final season of NBC's "30 Rock." In addition, star and executive producer Tina Fey told the magazine that Kenneth's mom will be played by veteran comedic actress Catherine O'Hara.

Kenneth has mentioned Cranston's character, Ron, in several previous episodes -- usually referring to him as his mom's "friend." However,  the cheerful page-turned-janitor did once claim to know Tracy Morgan's Tracy Jordan character like "the back of [his] stepfather Ron's hand."

Cranston may be attempting TV's first reverse-typecasting U-turn. He found unpredictable success as a drug kingpin on "Breaking Bad" after playing a comedic dad on "Malcolm in the Middle." But now that the AMC drama is drawing to a close next year, he appears to be about-facing. The TV Guide story hints that Cranston and O'Hara may become "30 Rock" regulars by possibly trading their native Stone Mountain, Georgia for Manhattan.

Season 7 of "30 Rock" begins Thursday, Oct. 4, at 8 p.m. ET/PT on NBC.
