Moltres appeared in the second feature length Pokémon movie, The Power of One.

Moltres, as depicted in an ancient legend, is the titan of fire (a computer on Lawrence III's ship confirms this). A couple of minutes later, Lawrence reavealed that that he was trying to capture the three legendary birds to bring out Lugia. Lawrence set out to get Moltres first. He bombed its island with ice bombs until Moltres got furious and flew away from its island to attack Lawrence. However, he captured Moltres and brought it aboard his flying ship.

Later, Lawrence captured Zapdos along with Ash, Misty, Tracey, Melody, Jessie, James, and Meowth. Ash tried to free Moltres and succeeded eventually. Moltres then freed Zapdos and the two birds burst out of the palace.

Moltres, along with Zapdos, started a fight between themselves as well as Articuno, the other legendary bird. When Lugia came up from the sea, Moltres worked with the other birds to put Lugia back where it came from. Later, Lugia rose again and none of the birds seemed to notice at first.

After that, Moltres didn't do anything except fight with the other birds but it returned to its island after Ash and Lugia silenced their fighting.
