The film, directed by German duo Michael Wech and Hanns-Bruno Kammertoens, was made with the blessing of the driver's family and will include interviews with them as well as companions and competitors, the filmmakers said.
Schumacher turned 50 on Jan. 3 but has not been seen in public since a skiing accident in the French Alps five years ago which left him with severe head injuries and in a medically-induced coma.
The film is in post-production, with international rights sales to be launched at the Marche du Film, a business event held in parallel to the cinema showcase on the French Riviera that kicks off on May 14.
Other films set to be introduced to buyers include a documentary about rock bank Led Zeppelin. As yet untitled, it will feature band members Jimmy Page, Robert Plant and John Paul Jones.
