James Cameron Joins Twitter, Feels 'Younger Already'

After an inspirational chat with Ryan Seacrest, director James Cameron has joined Twitter.

Tweeting straight from the heart, Cameron wrote in his inaugural post on Friday, "ryan seacrest told me I had to get on Twitter. So here I am. First tweet. I feel younger already."

The reportedly difficult, sometimes egomaniacal director of 'Avatar,' 'Titanic' and the first two 'Terminator' films didn't hesistate to poke fun of himself, either, writing, "I never tweeted before because I'm a long winded blowhard, and they don't allow enough characters."

Now he's retweeting, interacting with fans, and using hashtags like a boss.

Jim (we can call him Jim now, right?) has racked up 15,000 followers in his first five hours as Twitter user. But unlike some celebrity Twitterers (ahem, Kanye), Cameron is off to the races following a handful other accounts, including Seacrest, Jerry Bruckheimer, Tom Hanks, Oprah, his 'Avatar' star Zoe Saldana, writer/director Judd Apatow, Buzz Aldrin, and NASA (of course).
