What happens when you can't remember your lines?

In movies and stuff. Do you get fired? I know they re-do takes but what happens if you forget your lines constantly and is becoming a problem?

It's your job as an actor to remember your lines.
Some are good at doing improv if they slip up, but they keep it natural looking.
Sometimes directors like a good ad-lib

depends,..if you're old, they give you cue cards,...
Marlon Brando never learned his lines,..(supposedly) to keep things spontaneous.
I guess it depends on how valuable you are to the film,...your box office draw, or whatever.
Marilyn Monroe kept messin' up her lines on this one flick & got fired,...for bein' drunk or late or somethin'.

There's many actors who never remember their lines at first lol no they won't get fired unless they never learn them.
