Amitabh Bachchan says he's recovering at home from a injury suffered while shooting a film in southern India. The 80-year-old Bollywood superstar posted on his blog Sunday night that he sustained a rib injury while working in Hyderabad on the science-fiction film “Project K.” Bachchan wrote that he had broken rib cartilage and a muscle tear and he's been advised to rest. He said his work on the film was suspended until he’s healed. “Project K” is slated for release in 2024. Bachchan has acted in more than 200 Indian films since his 1973 breakthrough in “Zanjeer,” or “The Chain."
