The Killing of a Sacred Deer star Barry Keoghan has shown just how keen he is to land the lead role in upcoming superhero film Nightwing by dressing up as the DC Comics character.

An in-costume Keoghan shared the picture with fans on social media on Tuesday night, writing: "NIGHTWING the short movie coming soon."

The Dunkirk and Love/Hate actor's bid for top billing in the movie follows director Chris McKay's shout-out to fans last week, in which he sought their casting opinions.

Last month on Twitter, McKay wrote: "It's too early to talk about casting but in February... say around Valentine's Day maybe... I should have an update about where everything is with the first NIGHTWING movie!!"

McKay has plenty of history with DC Comics characters, having directed 2017's The Lego Batman Movie and worked as animation co-director on 2014's The Lego Movie

Chris McKay also directed The Lego Batman Movie

Keoghan's new film, the Irish revenge story Black 47, receives its world premiere at the Berlin International Film Festival later this week.

It is also the opening film at the Audi Dublin International Film Festival on Wednesday February 21.
