I read online that the Boar's Nest building was blown up in a 1994 movie called 'Forced to Kill'. I looked it up on IMDb, and found it stars Dukes stuntman Corey Eubanks, who also wrote and produced it. It also features Mickey Jones (B.B. Davenport in 'Granny Annie') and a brief appearance of fellow Dukes stuntman Al Wyatt Jr. Other stars include Michael Ironside ('Top Gun', 'Total Recall' etc.), Don Swayze (Patrick's brother), and Rance and Clint Howard (Ron's father and brother). I was surprised to discover the full movie on YouTube, but it's R-rated, so I won't post a link. What I will do is post a link to a short video featuring Corey talking about a stunt for the movie. The stunt shown takes place next to the Boar's Nest, but it's not visible in this clip:
The Boar's Nest building does appear very briefly near the end of the movie, but, contrary to the report I read, only a vehicle blows up and not the building. I managed to get a couple of grabs which show it to be in a very rundown state; the roof is sagging and it looks like it's been left open to the elements.
Knowing that the Google Earth timeline feature goes back to 1994 in this area, I decided to check it out. The image below is dated June 1st 1994, and shows a clear lot where the Boar's Nest once stood ("5" on the map). If the Boar's Nest was blown up, it must've been between the filming of 'Forced to Kill' and 1/6/94 - I'll keep looking!
