Oscar nominee Catalina Sandino Moreno is the latest actor to join the third, and now star studded, film in the “Twilight” saga.

“The Twilight Saga: Eclipse” starts shooting this month in Vancouver and will be released June 30, 2010. It’s being directed by David Slade, who previously directed “Hard Candy” and “30 Days of Night.”

Moreno, a Colombian actress, was nominated for Best Actress in 2005 for the film “Maria Full of Grace.” She also starred in Richard Linklater’s “Fast Food Nation” and Steven Soderbergh’s “Che.”

In “Eclipse,” she will play Maria, a vampire who plays an important role in the flashback for Jasper Cullen, played by Jackson Rathbone. During the Civil War, she and Jasper recruit an army of vampires.

She’ll join “Twilight” newcomers Bryce Dallas Howard, Xavier Samuel and Jack Huston as well as series regulars Robert Pattinson, Taylor Lautner, Kristen Stewart and others.

It’s no wonder all these stars want to be part of the “Twilight” phenomenon. The first film won 11 Teen Choice Awards earlier this week and the second one, “The Twilight Saga: New Moon” will be released November 20. The final trailer for the film will be in theaters this weekend attached to the Vanessa Hudgens film “Bandslam.”
