It is important to note that this report is based on set buzz and interviews, not reviews of the finished film. No critics have yet seen The Odyssey, so the performance's quality remains to be judged publicly. However, the comparison to Ledger — whose posthumous Oscar for The Dark Knight remains one of the Academy's most storied moments — has already reframed Morton's role from a small part in a star-studded ensemble to a potential Oscar contender.
Morton's casting as Circe was confirmed relatively late compared to the rest of the ensemble, and her role was deliberately kept under wraps in marketing materials . The official full-length trailer, released in May 2026, featured only three women — none of them Morton's Circe
. Her involvement was part of a group of cast members whose roles remained unannounced well into the marketing campaign
. Even as late as May 2026, fans on social media were asking why Circe was "missing" from promotional materials, with an Elle magazine feature on the women of The Odyssey notably not including her character
. This secrecy now appears to have been a deliberate strategy to preserve the impact of her performance — a tactic Nolan has used before, notably with Robert Downey Jr.'s role in Oppenheimer
.
Note on Charlize Theron: Sources conflict on Theron's role. The most recent authoritative sources — including Rotten Tomatoes' cast listing — list her as Calypso . Earlier reports and the IMDb page list her as Circe
. The preponderance of current evidence points to Morton as Circe and Theron as Calypso. The Odyssey also features Mia Goth as Melantho, Jon Bernthal as Menelaus, Benny Safdie as Agamemnon, and Bill Irwin as Polyphemus
.
Morton is a two-time Academy Award nominee — for In America (2003, Best Actress) and Sweet and Lowdown (1999, Best Supporting Actress) . Despite that pedigree, she has long operated as a character actor under the mainstream radar, with acclaimed but not widely seen work in The Walking Dead, Minority Report, and Synecdoche, New York
. The Empire interview and the Heath Ledger comparison have suddenly repositioned her as a potential Supporting Actress contender for the 2027 awards season. The combination of a small, high-impact role, the standing-ovation anecdote, and Nolan's awards track record (following Oppenheimer's sweep at the 2024 Oscars) creates a strong narrative for a "career-crowning" campaign. Again, this remains early speculation grounded in set buzz rather than reviews, but the ingredients are in place for one of the most intriguing acting stories of the coming awards cycle.
