Re: ...like to take screenshots of movies
You can on macOS if your watching in a browser (cmd+shift+4 - the standard way).
Noticed that there was engraving on the muzzle of Dead Pool's gun in the opening sequence (second film) but too small and fast to read. Screen-shot and got "SMILE" at the top of the muzzle and "WAIT FOR THE FLASH" on the bottom. Thought the humour was great even if it was mainly for the crew who did it
