Accidentally found this. Works for most of the closed pipes. Double tapping Esc will result in you being able to move while cinematic is still not over. If you do this too early, it won't work in some of the available scenes. Seems like it has a distance limit, so no need to rush it anyway. Usually, successful glitch will be indicated by sounds of character moving or by a little jump while still inside the pipe.

Why can't I get cutscene after jumping off the jet ski without waiting for Jimmy to walk?

Asking because I've heard by a chance Viper talking about this soflock now being resolved, do you know anything about it? Extremely annoying, killed 2 decent runs in a row

How to make it so it doesn't require you to sit on the seashark to progress, if you fly to the island in helicopter?
