Universal Studios and Amblin Entertainment should hire
Chloe Lourenco Lang as formerly known star since Stephanie back in her old show series from LazyTown Season 3 to 4 as well known actress.
So now this will be her first time to launch into new Universal Studios Major Global World phenomenon trending motion picture theatrical Universal Studios legacy of last saga for Back To The Future franchises
to be her first time villain character role of "Spike"
to be character of Griff's gang to chase Marty McFly Jr. (Tom Holland)
which is story just like matched from 1989 Back To The Future part II scene where future villains chases Marty McFly as they thought Marty McFly Jr that they didn't realize it was not really Marty Jr but Marty who traveled to the future, and so story saga to complete Marty McFly has already told his son about how to refuse to join in with Griff and his gang, and so his son learn to be brave and ultimate fight with Griff (Peter Gilroy) and his gangsters for this film but the line has to match same remake from Back To The Future part II but these new actors include villains include Chloe Lang and cast must do their own version acting but story should match the same with flying their hoverboards to be chase Marty Jr to find the way that made Griff and his gangs got distracted and flying accident that accident crashed into Hill Valley Courthouse before Hill Valley police arrive to arrest Griff and his gangsters to jail that claims destroyed Hill Valley's clock tower courthouse by accident fall into even only try to get while Marty Jr. escaped jumped off from his flying hoverboard into water to escape to avoid from them as this should kind of bit remake with permission from the original writer to use this for Back To The Future part 4 with using remake little bit scene based on Back To The Future part II (1989) to get permission from the original story writer to make this epic story to surprise audience fans can be excited and more immersive experience.
This would be best cast for Chloe Lang to be star role of Spike the one of Griff's gang in this Back To The Future part IV
