Every actor has to recreate themselves, in a sense, when they are playing a character. Bryan Cranston has a bit more experience at that then most. On 'The View' (weekdays, syndicated on ABC), Cranston talked about his character arc on 'Breaking Bad,' and transitioning from that character, a meth dealer/cancer patient, to playing Julia Roberts' husband in 'Larry Crowne.'

Playing Walter White is the big challenge, according to Cranston -- going from "Mr. Chips to Scarface," as his showrunner likes to say. "This is a show that's attempting to do something that's never been done in the history of television," he said. "And that's starting a character out as one type of person and over the course of the series, he's completely changed."

And if you're wondering, Cranston said there will be no going back. "There's no redemption for him," he said.

When Cranston got the call for 'Larry Crowne,' he was still in full Walter White mode, and thought he looked more like Roberts' father than her husband. He was afraid the audience wouldn't think they belonged together, so he plunged himself into a massive makeover and exercise program, which he found surprisingly enjoyable. "I had a mani-pedi," he said. "It was fantastic."

However Julia Roberts thought her appearance on 'Late Show' (Weeknights, 11:35PM ET on CBS) might go, it all went completely out the window when Tom Hanks ran onto the set asking if he could play.

He joined David Letterman on a trivia-based question for Roberts. Letterman asked her questions about Hanks, and Hanks had the answers already written down on sheets in his lap. Except, even this didn't go as Roberts might have expected.

"How many children does Tom have?" Letterman asked. Julia's answer: "Four, as far as he knows." Tom's answer: "Honestly, no idea. Actually, she got that one the closest."

"Is any of this really going to get people to go see our movie?" she asked between peals of laughter.

Matt Lauer noted Wednesday on 'Today' (weekdays, 7AM on NBC) that the teacher/student romance in 'Larry Crowne' isn't creepy because the two characters involved, played by Julia Roberts and Tom Hanks, are roughly the same age. But according to Hanks, that romance came down to a coin flip, and 'Larry Crowne' could have been a very different movie.

"The other teacher is George Takei, Mr. Sulu, and between the two of them, we flipped a coin to see, where will the romance begin?" said Hanks. "We're talking to a whole different mass audience, I'm telling you right now. Timely, without a doubt. But a different audience."

Lauer also asked Hanks about the press tour for the movie, which included an appearance on the Spanish-language 'Despierta America' where he danced with weather woman Chiqui Delgado while delivering the forecast. "I think our press junket is getting damn good reviews," he said.
