If Donnie Darko is one of your faves mostly because of Gyllenhaal himself (definitely don't blame you!), then consider adding Nightcrawler to your Netflix list. Just like watching a grown-up Donnie, main character Lou must navigate a dark, violent hellscape as a budding cameraman who sells his footage to news stations. A psychological thriller that makes you question the true difference between fact and fiction and what's ethical and what's not, this movie has all of Darko's nocturnal escapades and thrilling crimes, with a super-relevant angle.
