The images also depicted the two actors holding weapons that resemble the kind of sword that Blade uses. Based on this, the YouTuber made a suggestion that one of the actors could play Blade, while the other might be Blade's mentor, Jamal Afari.
In one of the posts, Gaffney added some hashtags including #ubisoft and #ubisoftgames which might also suggest that the actors were recording motion capture for a Ubisoft game.
However, Jor Raptor also drew attention to another photo posted by both Martin and Gaffney in which Gaffney is holding a clapperboard which names the production as "Marvel". The clapperboard also reveals the name of the director – B. Tariq – which is most certainly Bassam Tariq who is directing the Blade reboot which is scheduled for release in November 2023.
