The most well-known and common magazines when you want to find where to see a movie is Pariscope (http://www.pariscope.fr) 50 cents or l’Officiel des spectacles, 30 cents. In both guides you will find the list of theatres, concerts, cabarets, museums and of course the movies in all cinema.

Cinema tickets are about 8 € but usually half price on Mondays. New movies come out on Wednesday.
