1. Elle Parker. Very funny movie, with an interesting story. The 'director' was just a film student with a camera hanging out with his fairly unknown actress named Naomi Watts, and did a short film with her. Later, after she became very big, they went back and fleshed it out. It's got a really good funny/sad vibe, and she's gorgeous.
2. When we Left Earth. An excellent multi-disc documentary about the Mercury, Gemini, and Apollo programs, with a lot more in-depth stuff than you get in the typical shallow hour long documentary.
3. Stones in Exile . A really nice documentary about the Rolling Stones in the era where they were recording Exile on Main Stream.
4. Howard Goodall's Organ Works. A nice documentary about the history of the pipe organ. He has a number of other really good documentaries not yet out on DVD.
5. Young Adult. Which there's a review thread on here in this section. Just stumbled upon it and really liked it.
6. Herb and Dorothy. A documentary about two basically mid-middle class people who became the most important collectors of modern art on the planet pretty much, on almost no budget.
7. Sliding Doors. A cute romantic comedy with Gwennyth Paltrow. I presume it was one of those many that just slid by with minimal notice, but it's well worth a watch.
8. The Moog Documentary. Covers the history of Robert Moog and the evolution of the synthesizer. You may or may not like it depending on whether you want more technical stuff or more human level stuff. It leans towards the more human level side.
9. Jazz on a Summer's Day. A documentary shot one year at the Newport Jazz Festival. I forget the year, but I think late 60s, right? Some amazing music, even if you aren't particularly a big jazz fan.
10. Darkness on the Edge of Town. A really good documentary on the making of Springsteen's followup album after Born to Run, and arguably in my opinion his best work ever. Lots of participation by the folks involved.
11. Tom Dowd - The Language of Music. If you've not seen it definitely worth a watch. About one of the most influential folks in popular music, who died a few years back. He was the engineer at Atlantic Records for decades and worked on an incredible array of classic albums from Mingus to Aretha to Cream to Lynyrd Skynyrd to The Alman Bros to Ray Charles and on and on.
