Sham-Ir says that Jeannie's sister has never had a master, but in the TV series she often talked about disliking her master, so she must have had at least one.
During the show's original run, the network forbade Barbars Eden's navel to be shown on her skimpy costume. But in this movie it was allowed.
When Jeannie is under the pool table and rolls to face away from the camera, she nods her head (as when blinking), but there is no sound effect.

Goof: In scene where Jeannie blinks in a wall to prevent Tony from breaking up Roger and the dating service lady date. When Tony goes flying over the couch when he hits the wall you see that it takes Tony (Larry Hagman) a while to recover. When Jeannie has her finger in her mouth you can hear her say "did you hurt yourself?, but she is doing it under her breath as she pretends to bite her nail.
At Tony's house, when Dr. and Mrs. Bellows look out the front window to see Jeannie's sister kissing Biff... and they think it is really Jeannie who has just gone into the kitchen with Tony... you can see the kitchen door open behind them, but Tony and Jeannie closed it behind them when they went into the kitchen...
The episode's actual title is "My Sister, the Home Wrecker".
Major Healey actually calls his date "Tina" when he tried to introduce her to Dr. Bellows, but she is credited as Cindy.
In the dream wedding kiss sequence when they are spinning around, Larry Hagman opens his eyes briefly on the second go-round. He did the same thing during their first kiss in the premiere episode.
Inconsistency: The limitation about genies not photographing was introduced in episode 9, "The Moving Finger" but later ignored in episode 106, "The Biggest Star in Hollywood," before being reinstated in this episode.
Immediately after Jeannie tells Tony that she cannot blink, she does.
At the beginning of this episode, Larry Hagman is wearing white shoes with his uniform at the office, right before Jeannie blinks a wedding dress on Tony.
When Tony and Roger begin their search for the "imposter" and later drag Mrs. Bellows through the hall to Tony's office, Larry Hagman is wearing white clogs instead of black shoes with his uniform.
The heavy piece of wood which Tony is chained to disappears at one point, then reappears on his shoulders two seconds later.
