A | 记者24日从兰州大学获悉，该校物理科学与技术学院田永辉教授团队在光学数字计算领域取得重要进展。 Ranveer Singh’s spy thriller Dhurandhar, which hit the screens last week, is proving to be a box office winner despite criticism and pre-release opposition. The film has already collected an impressive Rs 160 crore worldwide, surprising trade experts and giving the industry a much-needed boost. Vijay raves about Dhuradhar The movie also won appreciation from actor Vijay Deverakonda, who shared his excitement on social media. “Watched Dhurandhar last night and completely enjoyed it,” he wrote. He praised the team further, adding, “The boys were all on fire,” showing his support for the cast and director Aditya Dhar. Vijay Deverakonda recently played a spy in his last release, Kingdom, and his performance was also highly appreciated. Naturally, the Arjun Reddy actor could resonate with the genre if Dhurandhar and how the spy film was written and conceived. Along with Ranveer Singh, the film features a strong ensemble cast including Akshaye Khanna, R. Madhavan, Arjun Rampal, Sanjay Dutt, Sara Arjun, and Rakesh Bedi. Each actor brings depth to the story, which mixes high-voltage drama with real-world tension. Dhurandhar inspired by true incidents Dhurandhar is inspired by actual events linked to India’s intelligence agency, RAW. The plot explores dangerous covert missions, crime syndicates, and geopolitical struggles surrounding Operation Lyari, a notorious gang-controlled zone in Karachi, Pakistan. The film blends action, emotion, and political intrigue, keeping viewers hooked throughout. The makers have already announced that the story will continue. The much-awaited second part is set for release on March 19, 2026, raising expectations among fans who are eager to see how the mission unfolds. With its strong word-of-mouth and rising audience support, Dhurandhar is expected to continue its solid run at the box office in the coming days.
