What does the woman imply when she says, "some of us in the department are going to see it tonight"?

W: Steve, you mentioned you wanted to see that new Janet Carmen film.
M: Mhm.
W: Well, some of us in the department are going to see it tonight.
M: That sounds great, but I probably won’t leave work until around seven. What time are you going?
W: We were planning on going at six thirty. Sure you can’t come to that?
M: Yeah...I haven’t finished this month’s sales report yet. Are there any later showings?
M: Well, there is another one at nine o’clock, but I don’t know if the others want to go that late. Or I’ll talk to them and let you know.
