Gibson did not make a public appearance during screenings held at the Riverwind Casino in Goldsby and Cameron University in Lawton. At the entrance of the casino — where the film was shown Friday to a mostly American Indian audience — reporters were kept behind partitions.
He arrived at Cameron on Thursday morning wearing a mask and wig so he wouldn't be noticed, university spokeswoman Amber McNeil said.
Jhane Myers, an Oklahoma City-based publicist who escorted Gibson, issued a statement saying Gibson was "deeply touched by the warm reception he has received while in Oklahoma."
Myers had said earlier in the week that Gibson had canceled the screenings planned for Oklahoma.
Gibson co-wrote and directed "Apocalypto," which is billed as an action-adventure film set in the last days of the Mayan civilization in Mexico. It will be released Dec. 8.
