The deleted scenes, which will most likely be included on the Blu-ray that hits stores November 9th, run about five minutes total. The first two are shorter, involving both Andrew Garfield and Irrfan Khan as Peter and Rajit Ratha tracking Dr. Curt Connors, plays by Rhys Ifans, to his lair in the sewers.
The third scene takes place in said lair, and it fills out some of the relationship between Parker and Connors, provides a bit more insight onto the Lizard's nefarious plan, and closes out Rajit's role. In the theatrical cut, the character simply disappears halfway through, but here, he clearly knows something about Richard Parker's research and just what makes Peter special. If you were hoping for some real meat, you're not going to be terribly satisfied, as no major questions are posed or answered, but there is a better idea of what didn't make the cut.
Attention has shifted as of late to the as-yet untitled sequel to The Amazing Spider-Man, which Sony Pictures long ago scheduled for May 2, 2014. Director Marc Webb and star Andrew Garfield are set to return, while Emma Stone is in negotiations to reprise the role of Gwen Stacy. Shailene Woodley of The Descendants, meanwhile, is in early talks to play the rebooted Mary Jane Watson, with an actor being sought to play the new Harry Osborn. The script is written by Roberto Orci, Alex Kurtzman, Jeff Pinker, and James Vanderbilt, who wrote early drafts of The Amazing Spider-Man.
