"We were busy [working in the kitchen] for pretheater, a mad rush to get them in and get them out in time to make curtain."
This quotes is from Anthony Bourdain's book describing that they are busy working for people going to theaters before the show.
My question is: Is "make curtain" a well known, well used expression to say make the show in time, or this is quite casual saying by Anthony? When I googled this expression, I could not find anything.
Thanks.

) for example on Tripadvisor: I think worse case scenario would be I wouldn't make curtain and would have to stand in back until interval.
