Brenda Blethyn stars in the upcoming drama film Dragonfly, which has been described as “shocking” and “violent” by critics
The latest trailer for Brenda Blethyn‘s “shocking” drama Dragonfly has just dropped and it’s already proving a massive hit with audiences after scoring 93% on Rotten Tomatoes.
The film also features Andrea Riseborough and Jason Watkins, with the storyline centring around Coleen (Riseborough) who becomes horrified by the treatment her elderly neighbour Elsie (Blethyn) is enduring, prompting her to volunteer her assistance without charge.
Nevertheless, the synopsis suggests that Colleen’s motives might not be quite what they seem. As suspicions mount, a devastating incident triggers a brutal chain of events that could irreversibly transform both women’s existence.
The trailer opens with Elsie recognising that looking after someone is “a lot of hard work” after Colleen volunteers her assistance. Colleen insists that it’s what neighbours are “supposed to do”, but the trailer swiftly shifts into darker territory as Elsie looks petrified by a telephone ringing in her house, and Colleen’s true intentions come under scrutiny from Elsie’s son (Watkins).
“I’ve been hurting all my life, Elsie, to be honest,” Colleen confesses, as we witness her menacingly observing Elsie through a glass panel in her front door, reports Chronicle Live.
Following its debut at the Tribeca Film Festival earlier this year, Dragonfly currently boasts a 93% score on Rotten Tomatoes. In our critique, we called the film “a powerful and compelling drama that explores those that society shuns, building to an ending you won’t forget”.
The Hollywood Reporter penned: “Is this tonal swerve a little gimmicky? Probably, and the film will not be to everyone’s taste. But it is a skillfully rendered exercise in terror.”
ScreenAnarchy remarked: “While cinema in general still tends to romanticise loneliness, Dragonfly shows it for what it is: a routine series of everyday, excruciating experiences that always build up to something that tends to be horrific, more often than not.”
The Guardian lauded it as “a stark, fierce, wonderfully acted film”, while Culture Mix observed: “Dragonfly isn’t just a ‘slow burn’ psychological drama.
“This well-acted movie about two lonely people and home caregiving takes an extreme turn in the last 20 minutes to a shocking ending that’s sure to be divisive.”
Last year, Blethyn spoke candidly about securing the role in the film after wrapping up Vera, reminiscing at the British Film Institute: “I was home, I hadn’t even unpacked my bag, and my agent called me and said, ‘Oh, you’ve been offered a film.’ I said, ‘I don’t want to do a film. I haven’t unpacked yet.'”.
“She said, ‘Oh, it is with Andrea Riseborough.’ I said, ‘Oh, is it?’ And she said, ‘And it starts next week because somebody had dropped out and it’s written and directed by Paul Andrew Williams.'”.
“I said, ‘Oh, well, I better have a little read of it just to… but no, I’m not doing it, but I’ll have a read of it.’ And I liked it, so I did it.”
Dragonfly premiered at Tribeca Film Festival in June 2025. A cinema release date is yet to be announced
