Spotted in The Rum Diary (2011) Paul Kemp types on a portable. I think it’s a Royal, but I can’t tell the model. Robert from ozTypewriter thinks it’s a Nakajima:

I haven’t seen the movie yet, but stills from it clearly show the typewriter being used by Depp as Thompson-Kemp is a Nakajima. The film is apparently set in Puerto Rico in the 1950s, long before Nakajima typewriters were first made. Whether Thompson would have found one in the US, or Puerto Rico, even when they were made, is questionable.
