Continuity mistake: When Teal'c walks into the Goa'uld force shield on the planet, he is forced off and he almost does a backflip. You can see that he would have hit the floor head/neck first. But when the shot changes, you see him land on the floor sliding on his back, as though someone had just pushing him over.
Continuity mistake: In the scene where SG-1 tries to get their note through the gate, watch Daniel. The camera cuts to him just before Jack slides down the zip line, and you can see small dots on Daniel's face - presumably the marks left when shot by the security system. However, Daniel has been taking cover since the alarms sounded and only gets hit when he tries to get to the gate after Jack is brought down. The next time Daniel appears on camera, his face is clear again and stays that way till the point in the scene where he, too, is killed by the security system.
Continuity mistake: Carter and Cadet Haley enter the Stargate and we see them through the "puddle." When they come out on The Other Side, their positions are reversed.
Answer: While the series was undeniably successful, filming it is a long process, taking many months of often long days. Anderson, after several years of doing this, wished to spend more time with his young daughter, who he felt he was neglecting, and requested that his role in the series be scaled back. Ultimately, he decided to leave the main cast altogether and only make occasional guest appearances.
