ABC Family is stocking up post-strike, picking up the six-hour longform “Samurai Girl” and a second season of hit series “Greek.”

Cabler will air “Samurai Girl” as a three-part programming event over the course of a weekend this August. Project, from ABC Studios, was previously shot as a one-hour pilot (which will now be expanded into one of the three two-hour segs).

“Samurai Girl” is based on the young-adult novels about a Japanese teen who discovers that her adopted father is really the head of the Yakuza — the Japanese mafia. She winds up training as a samurai to combat her father’s empire.

Project will start shooting this spring in Vancouver. Jamie Chung (“Dragonball”) stars as Heaven; other thesps include Brendan Fehr, Saige Thompson, Kyle Labine, Anthony Brandon Wong, Steven Brand and Kenneth Choi.

Frank Spotnitz, Bob Levy and Leslie Morgenstein exec produced the pilot, which was penned by Luke McMullen. ABC Studios also produces the teen and young adult-targeted cabler’s “Kyle XY.”

Production begins on “Greek” in early April on the show’s next batch of 16 episodes.

ABC Family will save 12 of those episodes for the show’s second season, which will air during the 2008-09 timeframe; the other four segs will also be produced for a block of first season episodes that begin airing on the cabler March 24.

Production will begin in early April on the show’s next season.

“Greek’s” initial 10-episode run last summer gave ABC Family its best-ever series ratings among adults 18-24; the last episode on Sept. 10 also posted the channel’s top-rated series telecast ratings with young adults.

ABC Family also found success online with the VirtualRush.com social networking website, which was launched as a companion to “Greek.”

Patrick Sean Smith created “Greek,” which comes from Piller/Segan in association with ABC Family.

Jacob Zachar, Spencer Grammer, Scott Michael Foster, Jake McDorman, Clark Duke, Dilshad Vadsaria, Paul James, Amber Stevens and Tiffany Dupont star.

Alloy Entertainment is behind the “Samurai Girl” franchise; Alloy’s Leslie Morgenstein and Bob Levy will exec produce as well.
