Continuity mistake: When Paddington leaves the boat he has stowed away in, there are significantly greater number of marmalade jars there than what he originally had (or could even fit) in his case.
Continuity mistake: When the family turn off the museum electrical system and then run away, their shoes are dry and do not leave wet footprints on the floor. Only when Millicent checks the electrics do the footprints appear.
Continuity mistake: On several occasions throughout the film when Paddington lifts his hat or takes it off briefly, the marmalade sandwich isn't there.
Continuity mistake: When Millicent is in the phone box, the glass near her mouth changes in between shots.
Continuity mistake: When Nicole Kidman hangs the cabbie Matt Lucas upside down, in the shots of her face from the front, her bob haircut covers her ears. In the matching shot of Matt, over Nicole's shoulder, her hair is tucked behind her ear.
Continuity mistake: When the family steps off the train, before meeting Paddington, the passers-by behind appear/disappear randomly between shots.
Continuity mistake: While inside the mail sack, Paddington jumps out of the truck and lands on the train platform. In the close-up a column has appeared right next to him.
Continuity mistake: During the old film from the beginning, when the explorer shows the snow globe to the bears, there's no snow falling, yet in the immediate close-up there is.
Continuity mistake: Just before the wallet thief smashes up the green VW Golf, there is a shot where you can see that the hubcap is missing from the passenger side front wheel. In a later shot however when it shows the VW Golf has come to a rest, the hubcap is now back on.
