The 49-year-old actor stars in Final Score, a thriller set around the final match at West Hams Boleyn Ground, or Upton Park, before the team switched grounds to London Stadium.
Bautista previously told Metro.co.uk how he knew absolutely nothing about West Ham before filming began, but now it seems hes a full blown convert – making an appearance in West Ham garb at their match against Wolverhampton Wanderers on Saturday (September 1).
Asked about how much he knew about the London team, Bautista said: Absolutely nothing! Absolutely nothing at all. I didnt grow up with football to begin with and I just didnt know anything about the side.

My first education in it was with the producer Mark Goldberg, who grew up in the stadium – which is where this whole idea stems from.
This is really paying tribute to the stadium that he loves so much, that he grew up with and has so many fond memories of. I think he started going there when he was five years old with his father. But other than that, I didnt know anything about it at all.
Bautista is known, outside his career as a professional wrestler, for playing Drax in Guardians Of The Galaxy, along with more minor roles in Blade Runner: 2049 and Spectre.
Final Score is released in UK cinemas and Sky Cinema on 7 September.
