"Glee" writer/co-producer Roberto Aguirre-Sacasa is working on a script for a third movie adaptation of the colourful stage show, reported Daily Star.
Gordon-Levitt is reportedly close to signing on as lovestruck hero Seymour.
The film has a history of big-name links - Jack Nicholson appeared in the 1960 version and Steve Martin portrayed a manic dentist in Moranis' 1986 movie, which also featured John Candy, James Belushi and soul legend Levi Stubbs as the voice of man-eating plant Audrey II.
