Continuity mistake: When Ben and Bea are flying to Australia for the wedding, Bea is in coach in a 2-aisle wide-body plane, but when Bea goes up to first class, it is a single-aisle narrow-body plane. (00:16:22)
Continuity mistake: Right before Ben jumps off the cliff, he drinks a small cup of coffee and places it back on a saucer that Jonathan is holding. When the shot cuts, the saucer is still visible in Jonathan's hand, but the cup cannot be seen on it. The cup then reappears in the next shot.
