The Sundance Film Festival started last Thursday and goes through Wednesday. Most everything is presented virtually this year, although there were a number of safety-in-mind in person screenings over the past few days.
Single tickets are $15. They are shown at scheduled times, but you also have access to them afterwards for 24 hours after the scheduled viewing begins. You have four hours to watch the film after you first begin your viewing.
Some things are free, such as some Q & As. You may have to create a free account to access some aspects of the Festival.
Here are links to two articles highlighting films from Yahoo and the LA Times. This might give you a good place to start, although you can go through the descriptions of the films and make up your own mind. After all, they were all chosen to be included in the Festival for a reason!
And if a film you are interested in has already premiered and had their second screening, just look for the film online to follow them and see where else they might be featured.
See you at the movies!
