SCI FI announced a July 10 premiere date for the second half of Eureka's season three and said the show will move to Fridays at 9 p.m. ET/PT from its previous Tuesday timeslot.

SCI FI also unveiled its slate of Saturday-night summer movies, starring Jason Gedrick, James Marsters and Peta Wilson.

The channel previously announced the July 7 premiere of its new series Warehouse 13, which will debut with a two-hour premiere starting at 9 p.m.

Eureka returns with 10 new episodes, picking up where it left off, with Jack Carter (Colin Ferguson) being removed from his job as Eureka's sheriff and Allison (Salli Richardson-Whitfield) announcing that she is expecting her recently deceased husband's baby.

Carter is also confronted by some challenging decisions on the home front where his daughter Zoe (Jordan Hinson) is concerned and encounters a new love interest with the arrival of Dr. Tess Fontana (guest star Jaime Ray Newman), who will supervise the re-opening of Global Dynamics' infamous "Section 5."

Ghosts Hunters International returns July 8 and will air Wednesdays at 9 p.m. This summer the team travels to Austria, Ireland, Italy, Chile, Argentina and the Czech Republic in pursuit of the truth behind bizarre supernatural claims. The first six episodes of season two will air this summer, with additional episodes continuing in 2010.

Ghost Hunters returns Aug. 19 and will air Wednesdays at 9.
