I was misinformed, Casablanca again

I've been watching the 2dvd Casablanca set a lot recently as well as reading Aljean Harmetz's book on the movie as I mentioned in an earlier post. I was listening to Roger Ebert's commentary track today and I've noticed something. Ebert keeps mentioning Bergman's comment that she didn't know which of the two men (Rick and Victor) that Ilsa was supposed to be in love with as if thats the same thing as not knowing which one of them she's going to leave with at the end of the picture. He is referencing Harmetz in this but misses that the problem for Bergman was emotional. Harmetz does a much better job at getting to the bottom of this and how it effected Bergman's performance. I think Ebert really should have taken this into account in his commentary but he seems much more interested in using it as part of busting the myth that the movie was ever intended to end differently*. During the last scene of the movie Ebert talks about Ilsa's confusion and this would have been a good point bring that up but he doesn't go back into it.

*Even if no one ever can really like Paul Henreid's characterization of the incredibly earnest Victor Laszlo. When I was younger and didn't understand how movie credits worked I was always confused by Henreid getting billing with Bogart and Bergman when it was obvious that Claude Rains was really the one who deserved to be up their with them for his performance as Renault.
