Last night, Dylan returned to the much-loved video service, with a 7-minute video called, "Life of a Hollywood Actor". In the video, Dylan takes us through his life as an unemployed actor, trying to find work.
"Posted a YouTube video for the first time in 8 years :o Check it out!" he wrote on Twitter.
We see Dylan do regular old sh*t we would do, like get petrol, drive aimlessly around town, and practice for a Frozen 2 audition (same).
So yes, we do see him sing "Let It Go".
We're assuming this video was taken after he had wrapped up the Maze Runner franchise and was looking for more work, because Dylan already has two new roles coming up.
