In case the second sentence sounds a bit enigmatic to you ("That Warners had a lucky break in the progress of world events that put the name of Casablanca on everyone’s lips is the answer to the surefire box-office smash the Hal B. Wallis production will enjoy."), here's a reddit/AskHistorian explanation: https://www.reddit.com/r/AskHistorians/comments/r2tmw0/theres_an_old_review_for_casablanca_that_states/ https://www.reddit.com/r/AskHistorians/comments/r2tmw0/there... A one-sentence summary would be that exactly when the movie was released, the Allied were landing in North Africa, and liberating Casablanca from the Nazis. But you would probably not regret reading the whole r/AskHistorian comment, it's a great one, like so many other comments on that subreddit.
