New dad Matthew McConaughey brought the 'Surf' to the sand in his hometown of Austin, Tx., Wednesday night at the premiere of his new comedy, 'Surfer, Dude' -- and ET was there!

Straight from the red carpet, ET talked to Matthew about his adorable son Levi and the joys of making his new film with his hometown friends. Co-star Woody Harrelson hailed Matthew as being one of the "coolest, greatest guys." And Matthew's mother Kay McConaughey told ET that her son is "a good father, trust me."

Opening exclusively in Austin theaters on September 5, 'Surfer, Dude' casts Matt as a dedicated soul-surfer who returns to Malibu to find his hometown vibe corrupted by new, high-tech sponsorship demands. Unwilling to take part in Virtual-Reality Video Games and Reality TV, he soon finds himself out of money, without sponsors -- and facing a flat surf in a biblical twist of fate.

With the help of his manager (Woody Harrelson), his mentor (Scott Glenn), his guardian angel (Willie Nelson) and his summer lover, (Alexie Gilmore), can Matt keep his cool? Or will he sell out?
