Ah now this looks like a great episode! so yep i'm most definitely excited about this ep
I might be speaking too soon but if it's just 1/5 as good as it seems it'll probably be the best stargate ep for quite a while(or ever!)
[spoiler]
Martin Lloyd (Willie Garson) returns to the S.G.C. looking for assistance from SG-1 with his feature film script. The team is reluctant, especially Lt. Colonel Cameron Mitchell (Ben Browder), who is excited about his next off-world mission which marks the 200th trip through the event horizon. However, when technical glitches prevent the team from gating off-world, they are stuck in the boardroom under the orders of General Landry (Beau Bridges), because the Pentagon believes a successful science fiction film about intergalatic wormhole travel will serve as a good cover story to keep the Stargate Program a secret.
