I guess none of the casablanca actors got along....

Although I've picked up a tidbit here and there, backstage gossip is something to which I pay little attention, so this is some I've never come across.

I have heard Peter Lorre say that he, Bogart and Greenstreet were great friends, and that he felt very alone after they were gone. And I've heard Bergman say about Bogart, "I've kissed him, but I didn't know him well." The stories about the chaotic nature of the production due to script changes that came on a nearly daily basis have achieved legendary status, so that must have been stressful.

In those days, of course, a busy actor's career consisted of starting a new job every couple or so months. I've never acted professionally, but on any job I've had, whether brief or lengthy, there were always some people who just didn't get along. I'm sure the intense nature of film making, what with the pressures of schedules, budgets and so forth making themselves apparent on-set among perhaps dozens of people who may be strangers to one another, can make that basic human circumstance acute.

One advantage actors working under those conditions have that employees in most jobs don't is the certainty that it never lasts long: usually over in a matter of weeks, after which they can move on. There's also a drawback: years and decades later, people are interested in it. 

But no one much cares who did or didn't get along at the ABC Tool & Die Company or the XYZ Food Mart.
