Variety.com is reporting two more confirmed cast members of J.J. Abrams' "Star Trek" movie. Australian actor Chris Hemsworth will play James T. Kirk's father, George Kirk. At 24, Hemsworth is three years younger than Chris Pine, who is set to play Jim Kirk, so the father role is likely to be portrayed in flashback.

In addition, a Latino actor who has played several vicious parts — including a gangbanger in "187," a hitman in "Traffic" and real-life killer Perry Smith in "Capote" — will join the Trek universe in the villain's camp. Clifton Collins Jr. will be "Ayel," the cohort and general to Nero, played by Eric Bana. Collins, 37, has a lengthy resume that includes a recurring role on Abrams' Alias.

Filming on the eleventh "Star Trek" film began last Wednesday, and will continue through March.

According to Variety, Hemsworth just wrapped the independent feature film "The Cache," opposite Sean Bean. Collins' credits include the upcoming indie features "The Perfect Game," "Horsemen," "Sunshine Cleaning" and "Still Waters." He just booked a supporting role in "Brothers" opposite Jake Gyllenhaal and Tobey Maguire.
