I assume you were asking about popular movies where the theme is woven into the story itself, not looking for any kind of rigorous introduction or analysis.
Blade Runner hits the theme hard with the robots who find out their memories are implanted and they have only lived a few years. Whether they have experience and inner life is explicitly considered, as is the question of morality in their treatment. The scene of the robot describing her childhood experience with the spider (sorry its implanted memory of the experience 👍🏻)
Secondly, Shutter Island can definitely motivate the idea and entertain, though not introduce and define the idea. That’s what I would suggest. Watching that makes one wonder about what this life is and can drive such a wedge between our experience and the world as to open people up to considering what the distinction is.
Good luck and enjoy.
DiCaprio arguably has a history of such:
His film about the subconscious, Inception, was entertaining and a bit thought provoking, especially for the non-philosopher. I don’t think it hits the hard problem though, perhaps a bit, esp if we consider the connection between Dreams and the Hard Problem of Consciousness, as in this paper so titled: https://www.researchgate.net/publication/340676299_Dreams_and_the_Hard_Problem_of_Consciousness
And then we have the (overly?) explicit effort to represent a psyche with multiple characters:
Does 'Revolver' Actually Suck?
Guy Ritchie's incoherent, possibly-about-Kabbalah gangster movie was panned by critics, but is it actually a misunderstood classic?
How did it get that bad reputation? I think because of what the Atlantic describes here. Nothing like ruining the stirrings of the imagination with explaination:
For viewers thick (or incredulous) enough not to get the message, Ritchie helpfully provides, as the credits roll, a series of brief psycho-spiritual testimonials in which luminaries such as Leonard Jacobson and Deepak Chopra explain
The moment I saw those clips my whole view of the film changed. If you do watch it, ask who the innermost character is. Even the film seems to be assuming his knowing and awareness of the others as given, but is it? And avoid Deepak part! 😉
