Pulitzer Prize-winning playwright David "Rabbit Hole" Lindsay-Abaire, continues to develop a screenplay for Columbia's "Spider-Man 4".
Sam "Evil Dead" Raimi will return to direct actor Tobey Maguire as 'Peter Parker', aka 'Spider-Man', a goofy teenager bitten by a radioactive spider, that gives him super-powers AND super-problems. 
Marvel comic book character villains anticipated to appear in the film, include 'The Lizard' and 'Electro'.
'The Lizard', aka 'Curt Connors' was a surgeon who enlisted in the service to help wounded GIs, but his arm was injured in a blast and had to be amputated. He then became obsessed with uncovering the secrets of 'reptilian regeneration' from his home in the Everglades, extracting a serum taken from the DNA of a lizard.
Successfully regrowing the missing limb of a rabbit, Connors ingested the serum, regrowing his arm and transforming into a reptilian monster.
'Electro', aka 'Maxwell Dillon' had ambitions of being an electrical engineer, taking a job as a lineman for an electric company. While repairing a power line still connected to its spool, Max was struck by lightning. Instead of being killed, the freak accident caused a 'mutagenic change' in his nervous system, allowing him to control vast amounts of electricity. After creating a costume, Max turned to a life of crime as 'Electro'.
Producer Laura Ziskin is aiming for a May 2011 release for the film, nine years after the first movie's spectacular debut.
Writer Alvin "Paper Moon" Sargent previously scripted the second and third films, with Michael Chabon, another Pulitzer prize winner, writing "Spider-Man 2."
Writer Lindsay-Abaire's "Rabbit Hole" play, currently being adapted as a feature for 20th Century Fox, starred actresses Cynthia "Desperate Housewives" Nixon and Tyne "Cagney and Lacey" Daly, winning four Tony Awards on Broadway including best play of the year...
