Casablanca was released on DVD earlier this week. This came as somewhat of a surprise to me, as I've already owned a copy on DVD for a few years now.
It turns out that the movie is being redistributed to coencide with its 60th anniversary, and this time there are even more special features on the two-disc set. Do I really need to buy another copy, though? The enhanced digital transfer isn't something I'm swayed by, but the new inclusions of commentary by Roger Ebert and the Looney Tunes homage cartoon "Carrotblanca," have me tempted.
If you don't already own a copy even if you've never seen the movie you should certainly pick one up. There's good reason the American Film Institute named it as the second best film of all time.
