Viggo Mortensen likes to hide references to his favorite sports teams in his films. In Green Book (2018) and Captain Fantastic (2016) there is reference to Viggo’s fave soccer team (San Lorenzo – “CASLA”) and in Falling (2020) there’s “Go Habs go” written on a diner wall (his fave hockey team)

CASLA = Club Atlético de San Lorenzo de Almagro, Viggo's favorite soccer team since childhood (he lived in Argentina as a child)
Habs = the Montreal Canadiens hockey team
