a couple different things.

less clearly, i remember Hanks trying to kill himself, the branch breaking and then you seeing the broken tree until the scene fades to black into the next scene. but I suspect this scene was actually from another movie.

more clearly, i remember Tom hanks’ character suicide-testing a wooden dummy to test the carrying capacity of the branch that is on a short but tall-enough cliff, but the dummy is too heavy and the branch breaks.

Branch can’t break twice, so I’m clearly remembering something wrong, but I “know” that whatever I saw happened fairly early on in the movie and was not his description of attempted suicide near the end of the movie.

I remember a fairly lengthy (2-3 minutes) action scene of him physically testing the tree off a cliff.

other people swear that neither scene was in the movie and there’s only the description of his attempted suicide at the end.

there are unsubstantiated rumors that the scene was in the theatrical version(which is the version i saw) but not in home releases.

I haven’t seen the movie since I saw it in theaters when it came out.
