Actress Rebecca Buller is listed as Jenny Olsen on the movie's IMDb page, leading to fan speculation that the character has been reinvented for Zack Snyder's film.
The most recent Man of Steel trailer featured a scene of Laurence Fishburne's Perry White and Buller running away from an explosion in Metropolis, suggesting that her character is a Daily Planet employee.
Buller's role in the film has yet to be confirmed by Warner Bros or any official sources on the production.
Jimmy Olsen, a photographer known as 'Superman's Pal', first appeared in Action Comics #6 in 1938.
He has previously been portrayed on-screen by Jack Larson, Marc McClure, Michael Landes, Justin Whalin, Aaron Ashmore and Sam Huntington.
Man of Steel, starring Henry Cavill as the DC Comics superhero, will be released in cinemas on June 14.
