I do have an anecdote about Glenn & movies. Before he sang Here's To Life in LA in 2012 he described the song as being epic, like a David Lean film. I completely understood what he meant. That man directed such masterpieces as Great Expectations, Bridge On The River Kwai, Doctor Zhivago & of course, Lawrence Of Arabia. I thought it was a perfect description.
I also have to say that while I'm not familiar with Don Henley's taste in films, I am sure he would enjoy them like anyone else. I did know the Last Picture Show reference from the 1979 Rolling Stone cover story. He said Linden was like that film. All you could do was dream (NB I've never seen it).
