Oliver Porter (or Mr. Porter) is the (former) main antagonist of the 2006 Christmas film Unaccompanied Minors.
Mr. Porter is always unhappy around the holidays, mainly because he hardly gets to spend time with his family during Christmas. In particular, he resents the holidays. He's not too fond of passengers, either.
Mr. Porter can also be devious at times, and he really shows it as he searches for Spencer, Grace, Donna, Charlie, and Beef after they escape from the UM room a second time.
Role in the film
Mr. Porter is first seen preparing for a vacation to Hawaii, having been allowed his first Christmas off in fifteen years. However, much to his chagrin, a blizzard cancels all flights to Hawaii, as well as numerous other flights, forcing him to go back to work again.
