{% for theater in movie.movietheater_set.all %}
{% for showtime in theater.theater.all %}
{{ showtime.time }}

{% endfor %}
Itβs confusing because of the related names. related name is the name the oposite entity will access the one where it is defined.
If you do:
class MovieShowtime(models.Model):
theater = models.ForeignKey(MovieTheater, null=True, related_name='showtimes' )
movie = models.ForeignKey(Movie, null=True, related_name='showtimes' )
Then you will access MovieShowtime like:
theater = MovieTheater.object.get(movie_theater='test')
for showtime in theater.showtimes.all:
print "Movie: {} - Time: {}".format(showtime.movie.title, showtime.time)
