- Supergirl‘s lead actor has revealed how she felt after being cast in the DCU
- Milly Alcock admitted she wasn’t sure she was the right choice for the role
- Elsewhere, DC Studios co-CEO James Gunn has denied rumors about the film’s budget
The main actor of the 2026s Supergirl the film has opened up about the fear she felt about being cast as Kara Zor-El in the DC Universe (DCU).
For the first time, Milly Alcock, who won the race to play Supergirl in January 2024, has revealed why she didn’t feel like the right choice for the character.
Speaking to Forbes Australia, Alcock admitted that while she was thrilled to be chosen to play the titular Kryptonian in the DCU, it took her a while to overcome the impostor syndrome that gripped her when she landed the role.
“I thought, ‘what have I done?'” Alcock explained. “I really struggled to believe I could do it. I even called the director [Craig Gillespie] saying ‘I don’t know how to be that person. I’m just me’.
“Eventually I realized the only way through was to trust myself,” he said House of the Dragon and Sirens alum continued. “I always believe that life is just in time. Things happen when they are supposed to, whether you feel ready or not.”
If any DC comics fans doubted that Alcock had the talent to portray the eponymous hero, such uncertainty was banished in the 2025s Superman film. At the time I actually thought I only need to watch 30 seconds of it Superman to have full confidence in Supergirl – and it’s all thanks to Alcock’s scene-stealing cameo in said flick.
If her performance, which DC Studios co-head James Gunn called “absolutely fantastic” in September, in Superman is anything to go by, we’re in for a real treat when Supergirl flies into theaters next June.
‘Not one iota true’: why James Gunn recently defended Supergirl
Speaking of Gunn, the DCU’s co-overlord has dismissed a report about the superhero movie’s apparent budget.
In his profile piece on Alcock, Forbes suggested that the film was previously known as Supergirl: Woman of Tomorrow cost $200 million But in response to a fan on Threads about the rumored outing, Gunn simply said: “[It’s] not even a little bit true.”
Gunn is no stranger to denying claims about his and Peter Safran’s nascent cinematic franchise. In fact, he’s regularly popped his head above the parapet to deny reports of various DCU Chapter One projects, so it’s no surprise to see him do so here.
Still, Gunn has denied it Supergirl costs of $200 million are significant.
Without knowing the ins and outs of Hollywood filmmaking, the general consensus among fans is that a film usually needs to make twice as much money as it costs to be profitable. In short: the smaller the budget, the less money a film must earn to be considered a commercial success.
If Supergirl‘s production budget was $200 million, and it would theoretically need to bring in $400 million in ticket sales to break even. The fact that its budget is apparently smaller means it has a better chance of not only covering its expenses, but also being profitable.
Of course, we’ll see if one of next year’s most exciting new movies becomes a box office success when Supergirl flying on June 26, 2026. But with rumors swirling Supergirl‘s first trailer may be released very soon, the reception it receives upon arrival may give us an indication as to whether it will be.
