Film, Theatre, and Media

Amitabh Bachchan portrayed Raj Malhotra, an ailing father abandoned by his ungrateful sons, in Baghban (2002). This was one of his most powerful performances depicting elderly parents' plight.

Amrish Puri played the iconic villain Mogambo in the film Mr. India, who famously delivered the dialogue 'Mogambo khush hua' meaning 'Mogambo is happy.' This became one of Bollywood's most memorable villain lines and is still quoted today.

Mel Gibson played Graham Hess, a former priest who loses his faith and becomes an atheist after his wife's death, in M. Night Shyamalan's Signs (2002). The film features an alien invasion, and Gibson's character ultimately rediscovers his faith by the end.

Prabhu played the role in the Tamil blockbuster Chandramukhi where a sentimental dialogue was delivered that later became comical. The film was a remake of the Malayalam film Manichitrathazhu and featured Rajinikanth in a different role.

Sanjeev Kumar holds the record for playing the most roles (nine different characters) in a single Hindi film - Naya Daur (though there's confusion with his role in Satyam Shivam Sundaram where he played multiple characters). However, Kamal Hassan actually holds the world record for playing the most roles in a single film (Dasavathaaram - 10 roles), but that's a Tamil film, not Hindi.

Kamal Hassan's character in the film Sadma (1983) and the song 'Ae Zindagi Gale Laga Le' became classics. The film was originally made in Tamil as Moondram Pirai and was also remade/dubbed in other languages. Kamal Hassan's performance was highly acclaimed.

Arnold Schwarzenegger famously played both protagonist and antagonist roles in different films of a franchise - as the hero Terminator in Terminator 2 and as the villain Terminator in the first Terminator film. The question specifically mentions 'in sequels' which refers to this franchise.

John Travolta and Nicolas Cage famously played protagonist and antagonist roles in the same film Face/Off (1997), where they swapped faces and identities. The question specifically asks about the same film (not sequels), making Travolta the correct answer.

Mukesh Khanna played the iconic role of Shaktimaan in the popular Indian television series of the same name. The show aired from 1997 to 2005 and became a cultural phenomenon, with Khanna becoming synonymous with the superhero character.

Kajol played the negative role (vamp) in the 1997 thriller film 'Gupt', which starred Bobby Deol and Manisha Koirala. This was a significant departure from her usual positive characters. Manisha Koirala played the female lead, not a negative role.

Priyanka Chopra played the vamp role in the 2004 film 'Aitraaz', which was inspired by the Hollywood film 'Disclosure'. She played Sonia Roy, a woman who falsely accuses her former lover of sexual harassment. Kareena Kapoor played the positive female lead role.

Shamita Shetty played the vamp role in the 2005 film 'Fareb'. Her sister Shilpa Shetty was not part of this film. The movie was a thriller where Shamita played a negative character. Udita Goswami and Neha Dhupia are other actresses who have played similar roles in different films.

Udita Goswami played the negative role in the 2005 film 'Zeher'. The movie was a thriller co-starring Emraan Hashmi and Shamita Shetty. Shamita Shetty played a different role in this film, not the negative one. Mallika Sherawat was not part of this cast.

Isha Koppikar played the vamp role in the 2004 film 'Qayamat: City Under Threat'. The movie was an action thriller and an unofficial adaptation of the Hollywood film 'The Rock'. Neha Dhupia, Rimi Sen, and Urmila Matondkar were not part of this film.

Neha Dhupia played the vamp role in the 2005 film 'Sheesha'. The movie was a psychological thriller where she played a negative character opposite Sonu Sood. Konkona Sen Sharma and Mallika Sherawat were not part of this film. Reema Sen is a different actress altogether.
