Everyone knows Casablanca.

That poignant movie telling us a story of love, sacrifice and the deprivation of rights in the midst of World War II .

Today we commemorate 34 years of the passing of Ingrid Bergman, lead Casablanca female character, and we want to pay tribute to this great actress pointing out 10 facts you probably did not know about this film.

1. Casablanca was entirely filmed in the States

The entire movie was filmed in the Hollywood studios, excluding the scene showing Major Strasser’s arrival (filmed in the Van Nuys airport) and some old stock footage views of Paris.

2. Ingrid Bergman was taller than Bogart

This is something you might not realize during the film. Humphrey Bogart had to stand on blocks or sit on cushions during their scenes together so the spectators would not notice the height difference.

3. The inspiration for the script came from a trip to France and Austria, not to Morocco

There are very few references to the real state of the country and specially of the city during the movie. Rick’s cafe was inspired by a nightclub in the South of France, packed with international clientele, many exiles and refugees and the prototype of “Sam”.

4. At the time the movie was filmed, there weren’t many expats in the city

Apparently, the route pursued by refugees out of Germany at the time did not end up in Casablanca. They usually passed by Vienna, Prague, Paris and London, or even Spain, but few of them reached the North African country.

5. Bergman wasn’t sure who she was meant to love

The script was not ready when the shooting started. None of the actors knew what was meant to happen and how the film would end, giving us a confused Bergman about the man she should love.

6. The song “As time goes by” was not created for the film

The song “As times goes by”, created by Herman Hupfeld 10 years earlier, was included in the original play, but Max Steiner -the music writer for the movie- wanted to replace it by his own composition. However, Bergman had already cut her hair short for her next film and they could not re-shoot the scenes, so they were forced to stick to the song.

At the end, it has been one of the most awarded songs in films of all the times.

7. “Play it again, Sam” is a misquotation

This sentence is not pronounced in the movie, not even once.

When Ilsa first enters Rick’s Café, she asks Sam to “Play it once, Sam, for old times’ sake.” After he feigns ignorance, she responds, “Play it, Sam. Play ‘As Time Goes By‘.” Later that night, alone with Sam, Rick says, “You played it for her, you can play it for me,” and “If she can stand it, I can! Play it!”

No trace of “Play it again, Sam” though.

8. The Rick’s Café we find today in Casablanca (Morocco) opened in 2004

The Rick’s Café we find today between the old Medina and the Port of Casablanca has taken its inspiration from the nightclub portrayed in the movie, but it was not until 2004 that Kathy Kriger, a former American diplomat in Morocco, transformed an old riad in what we find today.

9. They thought about a sequel

After the great hit of Casablanca, talk began of producing a sequel. One titled Brazzaville. After this, François Truffaut refused an invitation to remake the film in 1974, citing its cult status among American students as his reason.

10. The final scene

The background of the final scene, which shows a Lockheed Model 12 Electra Junior airplane with personnel walking around it, was staged using little person extras and a proportionate cardboard plane.
