Spider-Man 4 has been put on hold indefinitely.
Sony Pictures decided to delay the superhero sequel, which stars Tobey Maguire as geeky superhero Peter Parker and is directed by Sam Raimi, over concerns about the script, reports Variety.
"We will not start until we have it right - the feeling is we are not going to rush it to make the date," a Sony source told the film trade bible.
The decision means the fourth film in the series is unlikely to meet its announced May 6 2011 release date.
The film's director Sam hinted he would like to see Peter Parker become more mature.
"I've been talking with Tobey about where his character might grow to in this instalment," he said last October.
"[Parker] started as a little bit of a selfish, naive and insecure high school kid. In the second picture, [he] wrestled with his personal fulfilment versus that responsibility and, in the third film, I think it was a little bit about his growing hubris."
He added: "It's about the growth of that understanding, that it encompasses more than just his sense of duty toward others but he also has a sense of responsibility as a human being toward the ones he loves."
