In Inglorious Basterds, there are two parties of people planning on killing Hitler and everyone else at the theater. The first being Shoshanna and Marcel, who planned on burning the theater down, and the second being Col. Aldo Raine and the Basterdsm who planned on blowing everything up.
My question is: Did Marcel and Shoshanna know about the Basterds' operation and vice versa? Because, unless I missed something, neither would've succeeded without the other. The Basterds would've only succeeded in killing Hitler and Goebbels because Marcel wouldn't have locked the doors and so as soon as the two leaders were shot, the rest of the Nazi leaders would've fled. Marcel and Shoshanna probably wouldn't have succeeded because by the time the theater burnt down, the Nazis would've just sent one of the guards guarding Hitler and Goebbels down to unlock the doors and everyone would've fled as well.
Please explain if I'm missing something.
