**Strong ongoing demand for the limited 70mm IMAX screenings of Christopher Nolan’s The Odyssey is driving the 66% market-implied probability of another extension.** The film, the first feature shot entirely on IMAX film cameras, opened July 17, 2026, and quickly sold out weeks in advance at the roughly 25 U.S. venues capable of projecting the rare 70mm format. Universal and IMAX responded with a one-month extension through mid-September (around September 16), announced in late July after screenings sold out as far as seven weeks ahead. Recent updates show additional dates still being added and theaters noting that new showtimes “won’t last long.” The picture’s premium-format performance has been exceptional, delivering a record $52 million IMAX opening weekend and powering IMAX to its highest-grossing month ever in July. With only a handful of screens available and sustained fan enthusiasm for the expanded 1.43:1 aspect ratio presentation, traders see continued pressure on exhibitors to keep the run alive beyond the current September cutoff. Key near-term catalysts include weekly ticket sales data, any fresh theater announcements, and box-office momentum that could justify further date additions.
