Actors Michael Keaton and Mark Ruffalo will be on the red carpet in London facing reporters to promote their latest film, which sees them playing journalists themselves.
The duo will be joined by The Hunger Games star Stanley Tucci and director Tom McCarthy at the premiere of Spotlight on Wednesday evening.
The film follows the story of a group of journalists from the Boston Globe who exposed the widespread sexual abuse of children in the Catholic Church.
Real-life journalists Walter "Robby" Robinson and Mike Rezendes, who worked as part of the team of investigative reporters at the Globe, known as Spotlight, will also attend.
The Notebook's Rachel McAdams also stars in the movie but is not expected at the premiere, which is being held at a cinema in Mayfair.
The film has won best picture at the Critics Choice Awards and McAdams is nominated in the best supporting actress category at the Oscars for her role as journalist Sacha Pfeiffer.
The film has been nominated in a further five categories at the Oscars, including best picture, best directing and best actor in a supporting role for Ruffalo.
