The trailer, released Tuesday, contains scenes of concerts, the band in the studio, and their personal lives, including partying and fighting with each other as Mercury spiraled out of control.
The biopic, titled Bohemian Rhapsody, is due for release in United Kingdom cinemas in October.
The film will tell the story of Queen's meteoric rise into rock legend, the ways Mercury's personal problems almost destroyed the band, and their triumphant return and now-legendary performance on the eve of Live Aid.

Virunga is home to about a quarter of the world's remaining mountain gorillas, and the work of protecting them has proven unsafe . The Foreign Office now - and before the kidnapping - advises against travelling to the area.
If you'll recall, Singer was sacked from the film in December.
But despite its wealth of behind-the-scenes troubles, Bohemian Rhapsody is finally opening in theaters on November 2, 2018. Some Queen fans were less than pleased when Malek was cast to play the iconic singer, but he nails it - especially during Mercury's mustache era.
The project ran into more difficulty later on when the original director, Bryan Singer, was sacked after taking excessive time off for "health concerns".
Bohemian Rhapsody, a movie about the iconic 1970s and '80s rock band Queen, has been in development for nearly a decade.
In the trailer Malek is seen playing Mercury in different periods from the band's long career. Rami Malek stars as the iconic singer alongside Lucy Boynton, Gwilym Lee, Ben Hardy, Joseph Mazzello, Aiden Gillen, Tom Hollander, and Mike Myers.
