Ellen (1994) - 2 major mistakes

Continuity: When Ellen tells her friends that she is gay, she starts to digress. There is a bunch of wine glasses on the counter directly behind her. In several shots of the friends around the table, there are no glasses to be seen, but when Audrey says "I thought you had something important to tell us", she is holding a glass of wine. When you next see Ellen, the glasses are no longer on the counter, and the glasses are actually on the coffee table a moment later when the friends get up to leave. Yet no one actually served the wine out or got up to get any from the counter.

Visible crew/equipment: Just shortly after Ellen lets Paige in, when Ellen stands at the counter, Paige mentions handcuffs, and then Ellen's boyfriend comes out. As the camera pans to the right, you first see a streak of light in the middle and as the camera continues to move four or five stage lights can be seen. This can be seen on the season 2 DVD set very clearly.
