After announcing in May that they would be one of the strong supporters of HDR and UHD Blu-ray, Fox followed suit recently by releasing their four first movies in Ultra HD resolution with HDR metadata.
The movies are first released through M-GO, the streaming / download movie service. You need a compatible 4K Samsung TV to download and watch those movies as the company as an exclusive contract for this service.
The four movies that are already released are Life of Pi, Kingman : The Secret Service, The Maze Runner and Exodus : Gods and Kings.
Could it be the first four UHD titles from Fox when the format release ? Only time will tell, but at least we are starting to see more and more content in 4K become available.
