Jackson's last rehearsal was in Los Angeles two days before he died
The Michael Jackson film This Is It is to have simultaneous premieres in more than 15 cities around the world.
Cities hosting the premieres on 27 and 28 October include Los Angeles, London, New York, Berlin, Seoul and Rio de Janeiro, Sony Pictures said.
The movie is based on more than 100 hours of footage from rehearsals for the 50 London shows he had planned to do. Jackson died in June aged 50.
Names of the other cities hosting the premiere have not yet been released.
Hollywood films often hold premieres at different locations around the world but rarely at the same time.
"Michael Jackson has an army of fans everywhere around the world... we are giving the audiences an incredible opportunity to join together in celebration of Michael Jackson's incredible career," said Jeff Blake, chairman of worldwide marketing and distribution for Sony Pictures.
The Los Angeles premiere will take place on the evening of 27 October, while the London event will happen after midnight local time on 28 October.
In total, more than 25 cities will host premieres but not all will take place at the same time - they include Moscow, Tokyo, Sydney and Paris.
This Is It, directed by Kenny Ortega - the choreographer of Jackson's planned shows at London's O2 arena - offers a behind-the-scenes look at preparations.
The content is drawn from footage shot in Los Angeles between March and June.
The film will go on general release in cinemas on 28 October for just a two-week run.
The $60m (£36.4m) movie deal was made between Jackson's estate and concert promoter AEG Live and Sony Pictures.
Tickets for This Is It go on sale on 27 September.
The singer died after suffering a cardiac arrest on 25 June, weeks before he was to have started the concerts.
