You should watch Arthur Penn's Bonnie and Clyde (1967). Those two are household names but few people nowadays are familiar with the movie that made them famous. I was totally one of them, so I'm not judging. Turns out, the movie actually is worth watching. Both Faye Dunaway and Warren Beatty gave fine performances. It's especially cool because it's about real people who did all of this badass, yet criminal stuff. They weren't kidding.
Their relationship was very compelling. The infamous duo were a mere 23 and 25 (respectively) when they died and the whole tale only spanned about four years, which isn't long for all of this shit to have happened. I like the lust-at-first-sight deal that leads into I'll-follow-you-into-battle-even-if-it's-batshit-crazy thing. Add on the jail time trauma and we've got a solid story cookin' here. It's helpful to know the backstory to gain perspective on Clyde, at the least. If you can get through Faye's accent then you're good to go (it really is kinda annoying but she's supposed to be a poor broad from Texas back in the day so give her a damn break). Give it a shot.
