Actors perform, intoxicated with the three poisons i.e. passion (also lust, greed), aversion (also hatred) and delusion, and they do so, spreading it to their audience.
Then the audience too become intoxicated with passion (also lust, greed), aversion (also hatred) and delusion, and this will affect their future, naturally, because what one consistently thinks and ponders about, becomes the inclination of their awareness.
This applies to any movie or performance, with unwholesome themes. The unwholesome theme in this case is passion or lust (lobha).
"Apparently, headman, I haven't been able to get past you by saying,
'Enough, headman, put that aside. Don't ask me that.' So I will simply
answer you. Any beings who are not devoid of passion to begin with,
who are bound by the bond of passion, focus with even more passion on
things inspiring passion presented by an actor on stage in the midst
of a festival. Any beings who are not devoid of aversion to begin
with, who are bound by the bond of aversion, focus with even more
aversion on things inspiring aversion presented by an actor on stage
in the midst of a festival. Any beings who are not devoid of delusion
to begin with, who are bound by the bond of delusion, focus with even
more delusion on things inspiring delusion presented by an actor on
stage in the midst of a festival.
Thus the actor — himself intoxicated & heedless, having
made others intoxicated & heedless — with the breakup of
the body, after death,
is reborn in what is called the hell of laughter. But if he holds such
a view as this: 'When an actor on the stage, in the midst of a
festival, makes people laugh & gives them delight with his imitation
of reality, then with the breakup of the body, after death, he is
reborn in the company of the laughing devas,' that is his wrong view.
Now, there are two destinations for a person with wrong view, I tell
you: either hell or the animal womb."
SN 42.2
"Whatever a monk keeps pursuing with his thinking & pondering, that
becomes the inclination of his awareness. If a monk keeps pursuing
thinking imbued with sensuality, abandoning thinking imbued with
renunciation, his mind is bent by that thinking imbued with
sensuality. If a monk keeps pursuing thinking imbued with ill will,
abandoning thinking imbued with non-ill will, his mind is bent by that
thinking imbued with ill will. If a monk keeps pursuing thinking
imbued with harmfulness, abandoning thinking imbued with harmlessness,
his mind is bent by that thinking imbued with harmfulness.
