It’s a wonderful life: ACT processes
1. Contact with the present moment (and lack of): This I think is illustrated through George’s suicide attempt. He believes he has lost the money from the Building and Loan and that he his a failure and that now Potter will win (and it will be his fault). Such is George’s sense of dejection and impending rejection by the towns people that he attempts to escape by jumping from the bridge. Not only does George not want to be in contact with the present moment, but he wants to have never been born at al.
Georges decision at the end of the movie to have his life back demonstrates this beautifully I think. Before he realises the towns people have all come to help him out he takes his life back and contacts the present moment (which at that point is one of uncertainty over the missing money). He allows himself to be present and open to their criticism and the consequences of losing the money to find their love, help and support instead
2. Acceptance: This is perhaps demonstrated by George’s desire to keep living with the uncertain consequences he faces. I think the key message George takes from Clarence is that it is that upsetting things happen AND it's a wonderful life.
3. Defusion/fusion. Not explicit, but George does not explicitly decide that he has not let the towns people down, it is possible that he stills feels this way, but he has defused from it enough to allow himself to be present with the towns people and the consequences of losing the money.
4. Values: George values helping the town people. He values his family, he values making the town a better place and protecting it from exploitation from Potter
5. Commitment: In the movie, George not only values his values but is actively committed to not letting Potter exploit the town for his own financial gain. His actions are focused on changing the physical (i.e. fighting against Potter- a workable change agenda)
6. Self-as-context: not sure about this one, might there be a sixth process hiding in the movie somehwere
