Meh, Leaving Las Vegas is a great performance by Cage (maybe his best), I just don't think the movie itself is anything special or great.
The other one sure is an unusual choice. Not exactly my favourite movie, despite Bridget Fonda's presence...
Lord Of War - Eh, decent, I'd give it 6.5-7/10. Best Cage's movie based on what, imdb rating? To me it's just a decent movie and that's about it. Both Con Air and The Rock are better movies in my books while even National Treasure is more entertaining.
