This late fall has been a treat because we’ve received a new Steve McQueen (“12 Years A Slave,” “Widows“) week every week for the last three weeks; when does that happen? And they are all part of McQueen’s new five-film anthology series, “Small Axe,” based on the Jamaican proverb, “If you are the big tree, we are the small axe.” Three films have debuted at the New York Film Festival earlier this fall, and those three have now aired on Amazon Prime Video. The fourth film in the series is “Alex Wheatle,” inspired by real-life events about ordinary people showing courage, belief, and resilience to overcome injustice and achieve something transformative in their West Indian community.
