A contrary view....
For clarity, IMHO Tom Cruise was cool in Top Gun, and has gone down hill since then.
That said, some logical thinking...
He has spent his entire life working in cinema. Fair bet he has more knowledge than average about how movie making works - lighting, composing shots, etc. Astronauts are not technical slouches themselves and by their very nature are quick learners. Add in some live streaming for earth-bound directors to monitor the scenes. Pack along some green body suits and the station staff can be 'extras' in the scene, and have their body digitally edited to match the image of earth-based actors.
Russia was charging something like $80M per seat to get to ISS. I am thinking Elon Musk will be cheaper - otherwise we would have stayed with the Russians. I'll bet they could get an entire ISS sequence done for less than $100M. That's a lot, but it is not outside the realm of Hollywood possibility. Especially if the movie company says "Tom, we are flying you to the space station, but we aren't paying you for the movie", that will free up a big chunk of budget!
Would NASA allow it? Back to Top Gun, what was the Navy's enlistment in the late 1980s? Every GenX guy who signed up thought he would go Mach 2 and nail Kelly McGillis. As long as NASA gets to sign off on the plot line making them look good, I can see them buying the idea. Inspire a whole new generation of astronauts, that sort of thing.
Maybe even get the production company to produce a few companion documentaries as well - keep public interest in ISS positive. Inspire a whole new generation of tax payers, that sort of thing.
