Top Billing - S3-E5
Corrected entry: When Jon Lovitz tries to escape from the killers through a locked office door, the same door swings open two different ways and opens twice, despite being entered only once. As he's fumbling with the keys trying to unlock the door, he succeeds and the door opens towards him and away from the office. When the scene cuts to Lovitz actually entering the office, he's seen entering through the same door, which is closed again (despite just being opened) and now opens into the office, the complete opposite way it opened when he was shown unlocking it.
Correction: The doors that appear to be opening/closing out of sequence are two different characters opening two different doors. As Jon Lovitz is fumbling to open the office door, John Astin opens a door behind Lovitz, which opens into the room. Lovitz then opens the office door, which swings away from the office as it should.
