Recent reports of final screen tests narrowing the field to Jack Lowden, Callum Turner, and Josh O’Connor have driven trader sentiment toward Lowden, whose implied probability leads at 41.6% amid endorsements from Slow Horses co-star Gary Oldman and his Scottish background echoing Sean Connery. Callum Turner holds second at 25.4% on sustained industry buzz and recent career moves, while the 14.2% chance of no selection yet reflects the lack of an official announcement ahead of an expected 2026 reveal. These outcomes align with verified insider accounts of tests evaluating stunts, dialogue, and presence, though entertainment casting remains fluid until Amazon MGM confirms a decision.
