CCTV captures man walking straight through closed doors

CCTV footage filmed outside a shop in the US has caught a man walking straight through the shops closed doors.

The man wearing a dark hoodie, approaches the doors and carries on walking straight through them, as he does flash of light is seen and the video distorts.

As he leaves the shop, again by walking straight through the closed doors, there is another flash and video distortion.

A homeless person who is sitting outside seems to look at the man in disbelief as he walks away.

The video is very weird indeed but is it real?  I have my suspicions. Maybe a fake or a viral video to promote some upcoming movie or TV show.   If it turns out to be the real deal then this is amazing footage!
