Jack Lowden leads the market at 37% after recent endorsements from Slow Horses co-star Gary Oldman and podcaster Richard Osman, combined with reports placing him among the final four actors screen-testing this week for the role. Callum Turner sits second at 22.8% on the strength of his Masters of the Air action credentials and sustained betting interest, while Josh O’Connor’s inclusion in the reported tests has lifted his odds to 7.2%. The 22% probability of no selection yet reflects the ongoing process, with Amazon MGM and director Denis Villeneuve still evaluating stunts, camera presence, and dialogue before an expected announcement by year-end. Lower-priced names like Jacob Elordi have faded following reports they are no longer under consideration.
