You might like Malle's The Fire Within (Le Feu Follet, 1963), also based on Drieu La Rochelle's novel. Taste of Cherry (Ta'm e Guilass, 1997) and The Seventh Continent (Der siebente Kontinent, 1989) are very similar foreign language dramas.

Both adapted from plays in the form of Socratic dialogues, 'night Mother (1986) and The Sunset Limited (2011) focus explicitly on the pros and cons of self-deliverance.

Mishima: A Life in Four Chapters (1985), I Stand Alone (Seul contre tous, 1998), The Death King (Der Todesking, 1990), and Suicide Club (Jisatsu sâkuru, 2001) are much more graphic, but they all concentrate on raw emotion and/or disenchantment with materialism, a common theme in this sub.

If you need something lighter, Harold And Maude (1971) and Wristcutters: A Love Story (2006) are two excellent dark comedies about suicidal couples.

Leaving Las Vegas (1995) and Ordinary People (1980) are mainstream dramas in which the protagonists struggle with suicide. Girl, Interrupted and The Virgin Suicides might fall in this category, but they explore different themes.

The Bridge (2006), Boy Interrupted (2009), and How To Die In Oregon (2011), are three excellent documentaries, each distinctly covering a different topic on end of life. Frontline has covered right to die issues in several episodes, such as The Suicide Tourist (3 March, 2010) and The Suicide Plan (13 November, 2012.
