Given to films that were made for a budget of <$500k. Was a bit surprised how may of the films in here were nice little things I randomly caught some time or another so listing them all out seemed useful.
Order is by year with the winner of each year appearing first.
1999 - Treasure Island (Scott King)
Possibly wrong film:
2008 - Take Out
Last updated to include 2020 winners (36th Independent Spirit Awards)
