In 2020, Tucci starred in the British drama film " Supernova " opposite Colin Firth. The film explores the relationship between a couple played by Tucci and Firth as one of them succumbs to early onset dementia. The film premiered at the San Sebastián International Film Festival and since has received critical acclaim. Guy Lodge, critic for "Variety" wrote of their chemistry "Firth and Tucci are such reliable stalwarts that we tend not to regard their presence too closely in films these days: Almost invariably, they fulfill our expectations of their refined gravitas. But there’s something lovely and surprising in what they bring out of each other here, as they complement and reflect each other’s curtness, evasiveness and occasional spillages of tenderness in the way that long-term couples do."
