Saved by the Bell: Wedding in Las Vegas

Jessie (Elizabeth Berkley) only makes a brief cameo appearance towards the end of the film because Berkley was working on Showgirls (1995) at the time.

During the reception after the wedding, while Zack and Kelly are talking to their guests, one of the wedding guests (a female extra sitting at a table) can be seen "counting with expression". Basically, she must have had trouble faking/lip-syncing a conversation with the other extras, so instead she counts from one to about thirty, and uses facial expressions to make it look like she is having a real conversation.

When shown in syndication, this movie is split up into four half-hour "episodes".
