Oh, I get it. At first, I thought this was a reference to the 1996 anime movie. It didn't take hard for me to realize that it was a parody of how many awful video game movies there are. Seriously, the most acclaimed was "Final Fantasy: The Spirits Within" and that bombed! They ARE in fact making another Sonic movie. I'm fairly certain it will be animated.
Sedrich's hair should be more blue! I don't know if that other Sonic movie is coming in 2018. I've seen other parodies of live-action Sonic movies. They're also just posters, but boy are they funny! Writers will do anything nowadays.
