Return to prominence: 2000–presentIn 2000, Amitabh Bachchan appeared in Yash Chopra's box-office hit, Mohabbatein, directed by Aditya Chopra. He played a stern, older figure that rivalled the character of Shahrukh Khan. His role won him his third Filmfare Best Supporting Actor Award. Other hits followed, with Bachchan appearing as an older family patriarch in Ek Rishtaa: The Bond of Love (2001), Kabhi Khushi Kabhie Gham... (2001) and Baghban (2003). As an actor, he continued to perform in a range of characters, receiving critical praise for his performances in Aks (2001), Aankhen (2002), Khakee (2004) and Dev (2004). One project that did particularly well for Bachchan was Sanjay Leela Bhansali's Black (2005). The film starred Bachchan as an aging teacher of a deaf-blind girl and followed their relationship. His performance was unanimously praised by critics and audiences and won him his second National Film Award for Best Actor and fourth Filmfare Best Actor Award. Taking advantage of this resurgence, Amitabh began endorsing a variety of products and services, appearing in many television and billboard advertisements. In 2005 and 2006, he starred with his son Abhishek in the hit films Bunty Aur Babli (2005), the Godfather tribute Sarkar (2005), and Kabhi Alvida Na Kehna (2006). All of them were successful at the box office. His later releases in 2006 and early 2007 were Baabul (2006), Ekalavya and Nishabd (2007), which failed to do well at the box office but his performances in each of them were praised by critics.
In May 2007, two of his films Cheeni Kum and the multi-starrer Shootout at Lokhandwala were released. Shootout at Lokhandwala did very well at the box office and was declared a hit in India, while Cheeni Kum picked up after a slow start and was declared an overall average hit. A remake of his biggest hit, Sholay (1975), entitled Ram Gopal Varma Ki Aag, released in August of that same year and proved to be a major commercial failure in addition to its poor critical reception. The year also marked Bachchan's first appearance in an English-language film, Rituparno Ghosh's The Last Lear. The film premiered at the 2007 Toronto International Film Festival on 9 September 2007. He received positive reviews from critics who hailed his performance as his best ever since Black. Bachchan was slated to play a supporting role in his first international film, Shantaram, directed by Mira Nair and starring Hollywood actor Johnny Depp in the lead. The film was due to begin filming in February 2008 but due to the writer's strike, was pushed to September 2008. The film is currently "shelved" indefinitely. Vivek Sharma's Bhoothnath, in which he plays the title role as a ghost, was released on 9 May 2008. Sarkar Raj, the sequel of the 2005 film Sarkar, released in June 2008 and received a positive response at the box-office. His latest movie was Paa, which released at the end of 2009. Paa was a highly anticipated project as it saw him playing his own son Abhishek's Progeria-affected 13-year-old son, and it opened to favourable reviews, particularly towards Bachchan's performance. It won him his third National Film Award for Best Actor and fifth Filmfare Best Actor Award. In 2010, he debuted in Malayalam film through Kandahar, directed by Major Ravi and co-starring Mohanlal. The film was based on the hijacking incident of the Indian Airlines Flight 814. Bachchan did not receive any remuneration for this film.
