The film had been under production for two weeks when word came that Klaus Maria Brandauer (Out of Africa), the Austrian actor who'd been signed to play the rogue Soviet sub commander Marko Ramius, couldn't do it after all because of a prior commitment. Connery took the part instead, needing only one day for rehearsal.

...he didn't even bother pronouncing several of the words, much less saying them even remotely accurately. No Russian speaker would understand him without subtitles. In fact, when that movie came out in Russia, it was released with what's called voice-over translation, and typically anything that is clearly understood (or spoken in Russian) is left as is without translation (since you can hear all the original dialogue underneath the dubbing)... but not in the case of Sean Connery.
