Movies about coming of age?


I have seen almost every coming of age film, and I swear I can't find any I haven't seen. I want more, though. Care to give some favorites?

You mean me? Kei's cousin?
If you haven't, I heartily recommend Hayao Miyazaki's Spirited Away.
Look, Dr. Lesh, we don't care about the disturbances, the pounding and the flashing, the screaming, the music. We just want you to find our little girl.

There are some really good Coming of Age TV Series. Check out Skam, Freaks and Geeks, Skins, My So-Called Life, Buffy the Vampire Slayer, O Ninho, My Mad Fat Diary, Daria, if you haven't.

"Film is a disease. When it infects your bloodstream it takes over as the number one hormone. It bosses the enzymes, directs the pineal gland, plays Iago to your psyche. As with heroin, the antidote to Film is more Film." - Frank Capra

I'll second Holden's recommendation of Breaking Away, which is hands down my favorite in the genre.

Sixteen Candles
Pretty in Pink
Dazed and Confused

Bright light. Bright light. Uh oh.
When I Grow Up (1951) Low-key, forgotten and surprisingly relevant today. Needs to be restored to pristine condition; available now only on YouTube.

I'm not sure what exactly counts as such but here's some I think fit the bill (and yes, due to me being a horror fan many of these are horror themed):

The Little Girl Who Lives Down the Lane (1976)
Let the Right One In (2008)
Léon: The Professional (1994)
Ginger Snaps (2000)
Kick-Ass (2010)
The Reflecting Skin (1990)
Tigers Are Not Afraid (2017)
The Dark (2018)
Lemora: A Child’s Tale of the Supernatural (1973)
Tideland (2005)
Carrie (1976)
The Falling (2014)
Carny (1980)

These are probably a bit more marginal but at least they have similar themes:

Poison for the Fairies (1984)
Forbidden Games (1952)
Valerie and Her Week of Wonders (1970)
The Prodigy (2017)
Dark Touch (2013)

Also for the Freaks and Geeks series mentioned by @Holden Pike.
