The 'Downton Abbey' Movie is Already Off to a Very Promising Start

The long-awaited Downton Abbey movie doesn't arrive in theaters for another month, but it's already shaping up to be a box office hit.

According to ticketing company Fandango, the feature-length period drama performed very well when advance tickets went on sale Tuesday – outpacing the first day sales of this year's Quentin Tarantino event movie Once Upon a Time in Hollywood and last year's musical comedy sequel Mamma Mia! Here We Go Again.

“In its five-year TV run, Downton Abbey garnered an incredible global following,” Fandango's Managing Editor Erik Davis said in a press statement. “The first day sales are among the best we’ve seen for any movie this year. No doubt, fans have missed their favorite characters and are super-excited to see what new schemes arise in the upcoming film.”

According to Deadline, the movie is proving especially popular with older female audiences, a demographic which is more keen to plan theater trips in advance.

The trailer for the movie debuted in May, and whet appetites for the Royal visit storyline that we'd already heard about. David Haig, who played Bill in Killing Eve's first season (RIP), joins the cast as King George V's formidable-looking butler.

Imelda Staunton (Cranford, Vera Drake plays another new character, Lady Bagshaw, who seems to be a match for Dame Maggie Smith's sharp-tongued Dowager Countess.

Of course, Downton faves Hugh Bonneville (Robert, Earl of Grantham), Joanne Froggatt (Anna Bates), Laura Carmichael (Lady Edith), Michelle Dockery (Lady Mary), Elizabeth McGovern (Cora, Countess of Grantham), Lesley Nicol (Mrs Patmore), Dame Penelope Wilton (Isobel, Baroness Merton) and Jim Carter (Carson) - Staunton's real-life husband! – are all back for the movie, too. It opens in the U.K. on September 13 and then in U.S. theaters on September 20.
