Goofs

Frederik Vogeding's character is called Ivan Marloff in the actual movie, but is listed as 'Burke' in the credits for some reason.

At 31:12, Andrews reads a note from the late Sir Stanley Woodland. We see the note again when Nash steals it at 33:40. When Chan examines the same note at 42:17, the signature is in a very dissimilar hand.

When Charlie first reads the warning note that is put into his pocket on the ship it is in cursive writing with each letter connected to the next. Later when he shows the note, the handwriting is totally different.

While Charlie is playing with the children on the ocean liner, a dent in his hat disappears and re-appears.

Just before Charlie leaves the ship, a warning note is slipped into the pocket of his suit jacket. The pocket has a flap and the jacket fabric is a herringbone tweed. When he gets off the ship, he is wearing a different jacket. There is no pocket flap and the fabric is not herringbone.
