Tuntematon sotilas. The novel is highly recommended too.
If you let the bit about the time machine slide, Primer is a good candidate. I suppose you could call it a very realistic account of what would happen, if two kids in a garage accidentally did discover time travel.
Brings back memories of explaining to younger brother that 'This is Spinal Tap" was not real…and not being believed…
I second the Irish **Bloody Sunday ** (it not only looks real, it looks like it was made in 1972, which is amazing) and **Battle of Algiers ** (one of the bombing scenes in particular looks like they set off a bomb in a business and didn’t tell any of the people in it what they were doing).
Also, City of God, Z, Burn! aka** Queimada**, and Effect of Gamma-Rays on Man-in-the-moon Marigolds, a bit too realistic portryal of a dysfunctional 70’s family.
I strongly second that.
I too am a The Wire fan. It’s amazing. It’s a pity it’s not more widely known.
James Nesbitt puts me off Bloody Sunday but there was a film made around the same time that was called I think just Sunday that I liked.
City of God
The Road to Guantanamo
The Iranian film The Circle is another one.
