For anybody who’s seen the movie, Logan, there’s one scene that sticks out. If you haven’t seen the movie, then you may not want to keep reading (unless you’re not interested in seeing it but want to know the effect anyway). The scene is set in a Vegas hotel. Charles kinda loses it and Logan, quite literally, claws his way back to the room to save him.
The folks at Film Riot explore three ways to create this and similar effects. The first uses the same technique as in the movie itself. The other two, are slightly less conventional, and involve a back massager and an iPhone. Don’t laugh, that one is probably the best looking effect of the three.
