Jumping on the Internet-film bandwagon, Zac Efron and gal-pal Vanessa Hudgens spent a day earlier this week shooting a short film for web sensation FunnyOrDie.com.
And now, OK! can reveal a few details surrounding the soon-to-be posted flick.
The March 31 shoot occurred at the Hollywood Hills home of Zac's Hairspray director Adam Shankman and, in addition to Nicole Richie, co-stars Reno 911's Thomas Lennon as Zac's "Uncle Hank," who disrupts the HSM star's A-list party.
"It was a quick shoot and everyone had a blast!" an on-set source reveals to OK!.
Though it's ultimatey meant for Internet viewing, the short film will get its premiere in theaters as a lead-in to Zac's new film, 17 Again. The movie opens nationwide on April 17 and co-stars Matthew Perry.
