Mark told BuzzFeed Life that he's been an enormous fan of the movies for as long as he can remember. He has owns each of the three movies on VHS and DVD, and said he can't count how many times he's watched either of them. Beyond that, the movies played an integral role in his childhood.

Mark has cerebral palsy, and though he's fully mobile now, he was in a wheelchair as a child. Twenty years ago, with the help of a charitable organization, he traveled to Universal Studios with his family to meet Christopher Lloyd aka Doc Brown. Thomas F. Wilson, who played Biff Tannen in the triology, was also there as a surprise, and the group spent an entire day in the park.

A high point for Mark was riding the Back to the Future ride with Lloyd "continuously for three hours," while Lloyd quoted the movie.
