 Martin Lloyd ( Willie Garson ) , an extraterrestrial turned Hollywood writer , returns to Stargate Command looking for assistance from SG @-@ 1 with his script for the movie adaptation of the television show Wormhole X @-@ Treme , first featured earlier in the series in the episode " Wormhole X @-@ Treme ! " . The team , especially Lt. Colonel Mitchell ( Ben Browder ) , is reluctant to help . Mitchell is excited about his next off @-@ world mission because it marks his 200th trip through the Stargate . However , when technical glitches prevent the team from setting off on their mission , they are stuck in the briefing room under the orders of General Landry ( Beau Bridges ) , because the Pentagon believes a successful science fiction film about intergalactic wormhole travel will serve as a good cover story to keep the real Stargate program a secret .
