The short film categories can be somewhat frustrating in terms of availability. ShortsTV generally puts out a limited theatrical run the week before the Oscars, but even then it can be difficult to find depending on your area. As such, I must do my annual obligatory apology for not seeing every film. Daughter is the missing link this year, but it is not favored to win. So I will talk around the issue.
As for the others: Hair Love is on YouTube, Kitbull is on Disney+ and YouTube, Sister is on director Siki Song’s website, and Memorable is on Vimeo.
