The most talked-about trailer of the week is for Ben Stiller's remake of , the classic 1947 comedy starring Danny Kaye. With a strong cast including Kristen Wiig, Sean Penn, Shirley MacLaine and Adam Scott, the film looks like an eye-catching effects epic about a man whose daydreams take over his life. It opens in December. Watch The Secret Life of Walter Mitty trailer.

We also got a series of seven preview clips from the comedy We're the Millers, starring Jason Sudeikis as a guy who hires a stripper (Jennifer Aniston) and a couple of juvenile delinquents (Will Poulter and Emma Roberts) to play his family as he embarks on a dangerous drug-running trip to Mexico in order to repay his debt to a gangster. The film opens later this month you can watch all the We're the Millers clips here.

And finally, we had our first teaser trailer for Johnny Knoxville's Bad Grandpa, a spin-off from the Jack-Ass franchise in which Knoxville wears extensive make-up to play an 86-year-old who causes havoc everywhere he goes. Like Borat, it combines improvised gags with a fictional plot. It opens in October and, yes, it looks ridiculous. you should have a look at the teaser trailer.
