son finds his dad’s guns and money in basement wall. The neighbor abuses his wife and son and loves john wayne movies, I think the neighbors are Russian immigrants and their house gets burned down. Saw it sometime before 2006 I believe it came out around that time. The father fakes his death in the end. The movies was entirely English and I rented it.
Sounds like “Running Scared” with Paul Walker to me. Here’s the trailer:

It doesn’t show the specific scenes you mention, but I’m almost certain this is it. Peter Stormare plays the Russian who loves the movie “The Cowboys”.
