Gov. Fidel Herrera says several sets were built inside the Ignacio Allende prison in the port city of Veracruz and that the jail will be converted into a museum once Gibson is done filming.
In January, 1,500 inmates were transferred out of the prison to make room for Gibson's film, which began production this week and is tentatively titled "How I Spent My Summer Vacation."
Herrera made the announcement Thursday.
Gibson filmed his 2006 Mayan-language movie "Apocalypto" in Veracruz.
Herrera said Gibson also donated some of the sets from that movie.
