Portrayals
In Murder with Mirrors (1985), the character's name is changed to "Dr Max Hargrove" played by Anton Rogers. Here he is a fellow conspirator with Lewis Serrocold and Edgar Lawson. He has a dream of setting up a model reform institution but the Gilbranson foundation had refused funding for it. He and Lewis therefore strove to embezzle money from the foundation. When Miss Marple tried to ask Hargrove to analyse some nail clippings of Carrie Louise, he drew a gun because he knew she was closing in on the truth. The clippings would have revealed that she had not been ingesting poison and that the talk of her poisoning was a ruse to distract from the financial crime. Hargrove was stopped in time by Inspector Curry and Sergeant Lake but he managed to escape from them and get into his car. He attempted to drive out of the estate grounds but Sergeant Lake managed to close the gate. Hargrove's car slammed into the gate and exploded, killing him. The police also concluded that it was likely Hargrove who dropped the theatre lights on Miss Marple. Lewis Serrocold was, at the time of the attempted murder, still being interviewed by the police.

In the BBC 1991 adaptation of the novel which formed part of the Miss Marple series, Maverick's name is changed to Maseryk played by Saul Reichlin. Maseryk is a refugee Austrian Jewish psycho-analyst from Vienna.

In the ITV 2009 adaptation of the novel as part of their Agatha Christie's Marple series, Dr Maverick is played by Alexei Sayle.
