Blooper

During the Mardi Gras scene after Irena exits the crowd the number of streamers wrapped around her change in number and colors from long shot to close up.

On their first day out with Irena, the group has engine trouble and indicate that the problem is caused by the port engine. However, Felix adjusts the controls for the starboard engine.

Early on in the trip, Felix and Tony get into a fist fight, and Jimmy Jean continues to steer before eventually breaking up the fight. When the camera pulls back, it is clear that the boat is not moving.

In the opening title, the copyright date is given as MDCCCCLVII. The four C's, four repeating letters are illegitimate in Roman numerology. MCMLVII is canonical.

Doctor Sam finds a photograph of Felix, Tony, Irena and Jimmy Jean. However, it is impossible that the photograph could have been taken at all, as there was nobody else on the boat with them.
