By Cesar Arredondo Movies about a pair of estranged twin sisters, an ailing horse jockey, a traumatized monarch butterfly scientist, and a deaf family are among those with Latino actors in prominent roles in the lineup of the 2021 Sundance Film Festival. The program also includes films from Mexico, Spain, Argentina, and Brazil, and a documentary about actress Rita Moreno. Unsurprisingly, as most fests since the beginning of the pandemic earlier this year, Sundance will go virtual but also offer in-person screenings in about 30 cities across the United States “public health permitting,” organizers have announced. The 2021 edition offers a slimmed-down film selection program with over 70 features and 50 shorts compared to the 2020 festival. (The previous fest presented 118 features and 74 shorts in 2020. That means about a third fewer films this year. Episodic series were cut from eight to four.)
