Two questions

Hi teachers. I need your help. Thanks in advance. This may sound like a weird scenario, but it's for a horror story I'm writing.

Like she had done last night too, she stood in the dark movie theater lobby, staring dazedly at another movie poster hanging there.

Is 'another' ok to mean a different movie poster than the night before?

Is it ok to keep 'hanging there' or does it seem clumsy?
