If Tom is against Ritalin, then I agree with Tom.
I'm no fan of Ritalin myself. :-)
As a bit of background, I remember long ago that little Tommy Cruise was dyslectic in school (perhaps hyper, too). He had to learn the lines to Risky Business and Top Gun by having someone else read the script to him.
I also seem to recall that his 'religion' has lots of flash points with modern psychiatry and psychology.
So this is probably a big hot button for him. He should be a mature enough business man to just keep his mouth shut, though, on the whole topic. He's destroying not only his profit, but the investment of time, money and reputation of all of the other people who participated in this film.
Maybe he should take time out to write a scholarly tome on the evils of Ritalin. Movie-promotion interviews are not the time or place to be taking on that task.
On the other hand, another down week for movie openings is like music to my ears. ;-)
