Tom Holland-Austin Butler to collaborate for 'American Speed'-The Story of the Whittington Brothers

Certainly a story ripe for potential.  Based on the actors involved, looks like they will put some actual effort and money into it (though that also might increase the chances of padding the story). In the least, there has got to be some good 935 action going on.  You would HOPE they don't go with heavy CGI in it, but you never know.  Hopefully they build a bunch of replicas and use CGI to fill in the distant cars and backgrounds.

I am pretty confident they will skip the airplane part (years after the above and just one brother, not much of a story)...

I haven't heard this one yet. Like you said, there's a lot of promise here–especially if they decide to go more practical.

While there's no mention of a potential director, the named producer, Charles Roven, has some familiar film hits under his Producer credits on IMDB–namely Oppenheimer, The Dark Night and a slew of other superhero films.
