I too am all for all four LW films, heck I LOVE them. But as for Casablanca, I am sick and tired of studios re and re-re-releasing the classics. Like come one, can't you use those resources to put outfilms never released? Sure, Casablanca is a classic... it's one of my favorites, and probably, imho, the best film ever made (Godfather, Wind and Kane are right up there too).
But it has been released several times... like you said above, what more can they offer?
Sound of Music, Godfather, Wind, Oz, Zhivago... all of these have had multiple re-releases, and, trying to complete my collection of Best Puicture Nominees with the best availavle editions, I have been suckered into buying them all (and now I have a box full of coasters I can't give away. I tried to sell them in the sell/trade forum, but no offeres...)
The LW series was due for a MAJOR update. Hopefully, they give us some decent bonus features. (Don't know if they want to work with Mel Gibson though)... But If you ain't gonna give us anything better than that was on the DVD, I'm not gonna waste my time / money.
It's like, oh, say, Mutiney on the Bounty (1935). I have it on DVD, and it's enjoyable. But now it comes out on Blu-Ray with NO update to bonus features. So what is there to encourage me to purchase it on Blu-Ray, aside from a restored picture? The DVD was good enough for me. I was able to watch it.
Warners is particularly bad for this. Fox, too. I mean, Fox put out all of those terrific "Classic Collection" titles (although I thought they could have done a little better with some of the bonus features on some titles; some were very good.) Then, they go and release SEVERAL again on two-disc sets (Eve, Wrath). Paramount, on the other hand, won't put ANYTHING out (oh sure, they gave us Queen last year, but when is Wings comming???
It's very frustrating.
