It’s liftoff stateside for Defying Gravity after ABC acquired the 13-part sci-fi for its summer schedule from Vancouver producer Omni Film Productions and co-venture partner Fox Television Studios.

Canadian broadcasters CTV and Space, and the BBC and Germany’s ProSieben have already picked up the Vancouver-based series about eight astronauts on a six-year mission through the solar system.

A specific airdate might be announced next week, says CTV.

Gravity joins three earlier CTV series on or headed to U.S. network schedules: CBS’ Flashpoint and The Bridge, and NBC’s The Listener.

The sci-fi drama brings CTV and Omni back together after earlier collaborations on Robson Arms and Alice, I Think.

Gravity has an international ensemble cast led by Ron Livingston and Canadian Laura Harris (24), who play former lovers trapped together in space, and includes Malik Yoba (New York Undercover), Christina Cox, Florentine Lahme, Paula Garcés (The Shield) and Eyal Podell (24).

Omni Film’s Brian Hamilton and Michael Chechik share the executive producer credits on Gravity with James Parriott (Grey’s Anatomy, Ugly Betty) and Michael Edelstein (Desperate Housewives), both veteran ABC contributors.

Edelstein and Parriott based Gravity on the BBC docudrama Space Odyssey: Voyage to the Planets, for which they acquired the rights from British producer Impossible Pictures.

Production on the first season of Gravity wrapped on June 17 after a five-month shoot in Vancouver, with interiors at The Bridge Studios. The coproducers aim to do another two seasons, if the series performs on ABC and internationally.
