Do movies get to an age where coyright does not apply?

Yes, movies can eventually enter the public domain, at which point copyright no longer applies. In the United States, works published before 1923 are currently in the public domain, and for films created after that, copyright typically lasts for the life of the creator plus 70 years, or a set term of 95 years from publication for corporate works. Once this period expires, anyone can use the film without seeking permission or paying royalties.
