    The number of active movie screens--that is, screens showing films or booked to do so--is higher now than at any time since World War II.

    You do this because you are defining active movie screens and showing the info is not necessary.

  • English -

    The number of active movie screens -- that is, screens showing films or booked to do so -- is higher now than at any time since World War II.

    Two "en dashes" (--) need to have spaces before and after.

    Although some sources online will not take it, "em dashes" (—) can be used in the place of two en dashes.

    The number of active movie screens — that is, screens showing films or booked to do so — is higher now than at any time since World War II.

    In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

    I hope this helps a little more.
