Christmas Special 2017 - S2-E9
Continuity mistake: Price Albert's ice skates change after falling through the ice. Prior to the fall the ice skates have a curly blade front (appropriate for the time), upon emerging from beneath the ice the skates look like current models.
Continuity mistake: When Erik enters his father's office the clock on the wall shows 5.10pm. After they have been talking for a couple of minutes the clock still shows 5.10pm.
Continuity mistake: At the end when they are singing Mr Telephone Man at the BET Awards, Ralph takes his jacket off towards the end of the song. When the song is over, they all take a bow and Ralph has his jacket on. When they finish bowing, you then see Ralph without his jacket going to the front of the stage to pick the jacket off the floor.
Continuity mistake: When Selena was trying to write her song, in one shot she's writing with her right hand, next shot she's writing with her left, then back to right.
Continuity mistake: During the Medici brothers vs. Marco Bello confrontation near the end of the episode Lorenzo grabs a candlestick to defend himself against Marco Bello's knife - you can even notice a candle slipping off the candlestick. As Marco Bello turns to leave the chamber, however, Lorenzo's hands are empty and the candlestick rests on the table. In the next shot he's holding it again, with the candle sitting atop of the candlestick. (00:47:30)
Continuity mistake: Jack McKinney is lying in his hospital bed wearing his glasses when he is practising tying his shoe laces. He flings the shoe in disgust, at which time Jerry Buss walks in and hands the shoe to McKinney, whose glasses are now on the table.
Continuity mistake: When the princess moves between rooms, the door in the first room is left well open, but when the shot changes to the second room, the first door is almost closed. (00:05:40)
Continuity mistake: Tutankhamun and Suhad ride to the Mitanni city on a horse with no equipment at all, not even a saddle. Yet mysteriously when they need to stop for the night a large tent appears out of nowhere.
Continuity mistake: At the Chequers meeting in early 1944, Sir Bernard Montgomery is wearing the rank insignia of a field marshal. In the later meeting with the King in which the D-Day plans are announced, he is correctly wearing that of the lower rank of general. In fact, Montgomery was promoted from general to field marshal on 1 September 1944, nearly three months after D-Day.
Continuity mistake: When Nick's mom tells him to show Gypsy around she takes the cigarette away from her lips. A shot later it's back in.
