Philadelphia is a 1993 drama film directed by Jonathan Demme and starring Tom Hanks and Denzel Washington. The film tells the story of Andrew Beckett, a successful lawyer who is fired from his firm after being diagnosed with AIDS. Beckett decides to sue his former employer for discrimination and enlists the help of Joe Miller, a homophobic lawyer who initially wants nothing to do with the case.

One of the main themes of the film is the stigmatization and discrimination faced by people living with HIV/AIDS. The film portrays the fear and ignorance surrounding the disease at the time, as well as the prejudice and discrimination that Beckett experiences from his colleagues and the legal system. The film also touches on the issue of homophobia, as Joe Miller initially refuses to take on Beckett's case because of his own biases and prejudices.

Another theme of the film is the power of resilience and determination. Despite facing numerous challenges and setbacks, Beckett remains determined to fight for his rights and prove his innocence. He is also able to overcome his initial fear and shame about his diagnosis, and becomes an advocate for others living with HIV/AIDS.

Tom Hanks delivers a powerful performance as Andrew Beckett, and his portrayal of a man facing discrimination and illness with dignity and determination is both moving and inspiring. Denzel Washington's portrayal of Joe Miller is also noteworthy, as he convincingly portrays a man struggling with his own biases and prejudices.

Overall, Philadelphia is a poignant and thought-provoking film that tackles important social issues with sensitivity and nuance. Its portrayal of the stigma and discrimination faced by people living with HIV/AIDS, as well as the power of resilience and determination, make it a powerful and memorable film.
