Another day, another round-up of clips and trailers for your viewing pleasure! Today, let's take a look a new trailers for 'Transformers: Dark of the Moon' and 'Cars 2' (both with which, rather appropriately, premiered during the Daytona 500) as well as a clip from the indie flick 'Hesher,' starring Joseph Gordon Levitt and Natalie Portman, which will be making its way to SXSW in a couple of weeks. Let's start with the biggest and work our way down, shall we?

'Transformers: Dark of the Moon,' the third adventure of those wacky automobile robots, has at least one thing going for it: it looks huge, massive on a scale that dwarfs the last two films in this series, both of which felt absurdly huge themselves. It's difficult to imagine anything that would get us excited about this series again following the debacle that was 'Transformers: Revenge of the Fallen,' but the treatment of this latest entry as a strict "alien invasion movie" works like gangbusters (at least in the advertising).

This 30-second spot isn't too different from the ad that ran at the Superbowl, but there seems to be enough new stuff to make it worth a half-minute of your time. Check it out (as well as the footage from 'Cars 2' and 'Hesher') after the jump!

Next up, here's a new minute-long trailer for 'Cars 2,' the sequel to arguably Pixar's least interesting film (at least among animation aficionados). At the risk of being profoundly, unfairly negative, what's on display here doesn't look good: crass jokes, a lot of screaming, simple slapstick and more Larry the Cable Guy than a sane person can tolerate. Of course, we can't judge a film based on a trailer alone, but coming from the company that made such beautiful and sophisticated films like 'Toy Story 3' and 'Up,' this looks like one big step backwards. However, when toys from the first 'Cars' film alone have made over $8 billion for the company, it must be tough to say no.

Finally, at the exact opposite end of the spectrum from giant robots destroying the world and animated cars prat-falling into vats of oil, here's a clip from 'Hesher,' the story of a weirdo loner (Joseph Gordon Levitt) who meets up with a shockingly nerdy-looking Natalie Portman for what we can assume are romantic, emotional shenanigans. The film is the feature debut of Spencer Susser (check out our review from Sundance 2010) and before it lands at SXSW for its latest festival appearance, check out a new short NSFW (language!) clip from the film, which finds Levitt rescuing Portman from a predicament in a manner that can only be described as, er, unique:
