Murphy plays a literary agent who stretches the truth but finds things change after he meets a New Age guru played by Curtis. A magical tree appears in Murphy's backyard and a leaf falls from the tree each time he utters a word and when the last leaf falls both he and the tree will die.
Curtis appears to escape most of the criticism. The Screen Rant movie website said this about Murphy's fellow actors: "For such a flimsy and poorly-executed concept, A Thousand Words manages to collect some talented players ... Cliff Curtis (Die Hard 4, Training Day) is a much better actor than his presence in this film would suggest".
The New Zealand movie Boy, co-produced by Curtis, is currently screening in the US and receiving good reviews. It was released the same time as A Thousand Words and The New York Daily News called it "quirky" and "a valid effort to explore the difficulties in coming of age during tough times".
Curtis could not be reached for comment about either movie but his New Zealand agent Gabriella Larkin-Bruce said she was unaware of the criticism of A Thousand Words.
Ms Larkin-Bruce said she usually received movie scripts for Curtis. "But this was one that was obviously picked up by his American agent - particularly if it was an Eddie Murphy movie," she said.
Curtis' next project is the TV drama Missing, which premiered in the US this week. Additional reporting APN News and Media
