Actor Ryan Phillippe thrilled fans on Thursday (04Apr13) by joining microblogging site

The Cruel Intentions star's first tweet alerted fans to his directorial debut Shreveport, an indie thriller which is set for release later this year (13).

It read, "Really excited for you guys to see my directorial debut Shreveport! Info and pictures will be released exclusively through my new twitter!"

Phillippe followed the tweet up with a message about his new documentary, Isolated, which follows five professional surfers as they travel to New Guinea in search of undiscovered waves.
