Tor Einar Gudmestad was born August 13th 1996, in the city of Stavanger in Norway. He grew up in the nearby smaller city Jørpeland, just a ferry-trip away from Stavanger, with his ultimate idol being the fictional character MacGyver (1985) played by Richard Dean Anderson in the mid 80's, which he later ended up parodying in his own small web-series, called "MacGudmi". He states now he never wanted that cult-fame which the series got, and he still to this day (2018) is greeted on the streets as "MacGudmi", which he now only jokes around with, calling it a "very weird time in puberty".
He is the son of Borgny and Tor Bjørn Gudmestad, and he has five older siblings. Regardless of his passion for acting, none of his family members has acting experience, except his mother who played in a sketch-comedy group while he was only one year old. Tor developed early on the passion for acting and making jokes in front of a crowd, and he ended up attending the local sketch-comedy group at young age, directed by the same man who directed his mother a decade earlier. Studying drama in high school seemed as the perfect way to go, and so he did, at Stavanger Cathedralschool in Stavanger.
He started working on the idea of writing and making a movie back in 2012, after seeing his all-time favorite actor,Leonardo DiCaprio, in the psychological thriller Shutter Island (2010), which back then became his favorite movie of all time. (That title now belongs to Interstellar (2014)) He started writing the script to his own psychological thriller, Sannhetens løgn (2015), in the first semester of high school, and finished it by the end of 2013, in his second semester. The project got huge support from locals, and financing the movie ended up being not a problem, making the possibilities "endless" for a young director.
Early 2016 he was accepted into Rose Bruford College in London, England alongside 27 other applicants out of over 2000. He moved to England September that year to start his training.
