Morgan wrote television scripts during the 1990s, including an episode of Rik Mayall Presents... and the Comedy Premiere The Chest. He wrote the screenplay to the romantic comedy Martha, Meet Frank, Daniel and Laurence (1998). He also served as additional writer for Madame Sousatzka (1988), co-writer on the short film Dear Rosie (1990), and wrote re-writes for the comedy King Ralph (1991). In 2002, Morgan had some success with the TV series The Jury (2002). In 2003, Morgan broke through with The Deal, a television drama about the power-sharing deal between Tony Blair and Gordon Brown that was struck in the Granita restaurant in London in 1994. Blair was portrayed by Michael Sheen, who would return to the role of Blair in The Queen and The Special Relationship.
In July 2009, filming began on the television film The Special Relationship, the third film of Morgan's "Blair trilogy". The film focuses on Blair's (again played by Michael Sheen) relationship with US president Bill Clinton, played by Dennis Quaid, between 1997 and 2000. The film also features Hope Davis as Hillary Clinton and Helen McCrory as Cherie Blair. Morgan was originally scheduled to direct the film (making his directorial debut) but pulled out a month before filming began. He was replaced by Richard Loncraine.[7] The film debuted on HBO on 29 May 2010. Barry Morgan of The Associated Press declared, "With its well-chosen cast and high production values, “Relationship” is an especially thoughtful, revealing and honest account of power and politics."[8] The film also received positive reviews overall receiving an 83% on Rotten Tomatoes with the consensus reading, "Well-cast and compellingly directed, The Special Relationship offers an intelligent look into the complex dynamic between two world leaders."[9] The film received five Primetime Emmy Award nominations including, for Outstanding Television Movie. Morgan was nominated for Outstanding Writing for a Limited Series or Television Movie losing to Adam Mazer for another HBO television movie You Don't Know Jack (2009).
In 2008, Morgan was initially set to adapt the John le Carré's Tinker, Tailor, Soldier, Spy into a screenplay for Working Title Films but dropped out and served as the film's executive producer.[10] In June 2009, it was announced that he would be the co-writer of Skyfall, the 23rd James Bond film.[11]The Daily Telegraph's Mandrake diary reported in April 2010 that Morgan had quit the production after Sam Mendes was hired to direct, and that Patrick Marber would replace him. MGM dismissed the Telegraph's claims as speculation.[12] In the end Morgan did not receive credit but rather it was Neal Purvis, Robert Wade, and John Logan who were credited as the film's screenwriters. He has since finished the script for Hereafter, a supernatural thriller "in the vein of The Sixth Sense". DreamWorks bought the screenplay on spec in March 2008.[13] The development was later transferred to Warner Bros. and filming began in October 2009 under the direction of Clint Eastwood.
Morgan's next feature film would be BohemianRhapsody (2018), a biopic about rock musician Freddie Mercury (portrayed by Rami Malek), the lead vocalist of the rock band Queen.[15] Morgan has started writing the screenplay in 2010. The film was a massive box office success earning $903.7 million. The film however received a mixed critical response with critics praising Malek's central performances but criticising its editing, directing and pacing. Time Magazine film critic Stephanie Zacharek wrote, "In strict filmmaking terms, Bohemian Rhapsody is a bit of a mess. Some of its scenes connect awkwardly, and it hits every beat of disaster and triumphs squarely, like a gong."[16] Despite its criticism, the film received various awards including four Academy Awards for Best Actor, Best Sound Editing, Best Sound Mixing, and Best Film Editing.
