The Day of the Jackal (1973)

Plot hole: When the French conclude - incorrectly - that Charles Calthrop is the Jackal, they contact the British authorities and obtain his file photograph from the passport office. The photograph is of Edward Fox in character as the Jackal - but it shouldn't be! The Jackal and Calthrop have no connection. The Jackal never used his identity and did not apply for a false passport in his name. The photo should have been of Edward Hardwicke in character as Charles Calthrop, who appears in the closing minutes of the film. The two actors do not look anything like each other.

Lebel: It's obvious that the Jackal has been tipped off all along, and yet he's decided to go ahead, regardless. He's simply challenged the whole lot of us.
Minister: Are you really suggesting that there's a leak from inside this room?
Lebel: I can't say. But we think that the Jackal is now in Paris with a new name and a new face, probably masquerading as a Danish schoolteacher.

Trivia: Fred Zinnemann wanted the Jackal to be played by an anonymous actor, so he passed over established stars such as Michael Caine, Roger Moore, and Jack Nicholson in favor of Edward Fox. He later admitted that his decision might have been what contributed to the film's sub-par performance at the box office.

Question: I have seen this movie many times, but one question continues to bother me: How did the Jackal plan to escape if he was successful in shooting the president? (He had already removed his disguise).
