The cameras haven't started rolling, but Domhnall Gleeson has already been tipped to receive his first Oscar nomination for his lead role in the upcoming biopic of Winnie the Pooh creator AA Milne. 

US magazine Vanity Fair describes Goodbye Christopher Robin as "the kind of uplifting, nostalgia-heavy project that plucks at the heartstrings of Academy voters" and feels that Gleeson's time to be on the Oscars shortlist is fast approaching after a brilliant year on screen - and at the box office. 

Two of the Dublin actor's most recent films, Ex-Machina and The Revenant, were among this year's Academy Award winners, while Brooklyn and Star Wars: The Force Awakens were both Oscar-nominated.

Goodbye Christopher Robin will see him working with filmmaker Simon Curtis, who directed Michelle Williams and Kenneth Branagh to Oscar nominations for the 2011 Marilyn Monroe biopic My Week with Marilyn

The Academy's love of actors playing real-life authors is deep-rooted with Jason Robards (Dashiell Hammett), Daniel Day-Lewis (Christy Brown), Jim Broadbent (John Bayley), Nicole Kidman (Virginia Woolf) and the late Philip Seymour Hoffman (Truman Capote) among those honoured with Oscars in the past.

Vanity Fair adds that Johnny Depp received a Best Actor nomination in 2005 for his performance as Peter Pan creator JM Barrie in Finding Neverland, while Bryan Cranston was shortlisted this year for his role as screenwriter Dalton Trumbo in Trumbo.

Goodbye Christopher Robin will focus on the sometimes difficult relationship between Milne and his son Robin, who was the inspiration for the character of Winnie the Pooh's human friend, Christopher Robin.

Gleeson's About Time co-star Margot Robbie will play Milne's wife, Daphne, and the film will show how the family and their nanny Olive became swept up in the international success of the Winnie the Pooh books in the aftermath of WWI.

While the finished film is some way off, Gleeson's A-list momentum continues early next year when he appears opposite Tom Cruise in Mena, which is based on the true story of the late drug smuggler and pilot Barry Seal. Seal, played by Cruise, was recruited by the US Drug Enforcement Agency to provide intelligence and Gleeson plays his handler, Monty Schafer. The film will be in cinemas from January 6, 2017.
