According to reports, Williams has joined co-stars America Ferrera and Ana Ortiz in their crusade to bring an Ugly Betty movie to the big screen.
"We did not want to leave. Our last week, none of us wanted to leave the table. None of us wanted to finish the words we were saying," Williams said about the final taping of the show.
She added: "It was an extraordinary group of people, the ensemble was great, the directors were great - the writers - the whole team. It was unique. Yes, an Ugly Betty movie, absolutely."
The final episode of the comedy aired in the US last week.
