Marissa Tomei's casting as Aunt May in the "Spider-Man" reboot has received online backlash as the Oscar-winning actress was deemed too young and too sexy to play the role.

The reboot will also feature the youngest webslinger yet as 19-year-old Tom Holland has been named as the lead character.

"According to some complaints, Tomei, 50, is just too young and attractive to portray the character - who was played in Sam Raimi's 2002 film Spider-Man by the then 74-year-old Rosemary Harris, and by a 66-year-old Sally Field in 2012's The Amazing Spider-Man," said The Guardian.

"Others argued more seriously that the casting was a byproduct of Hollywood's negative attitude towards age," it added.

Dave Turner tweeted, "Marisa Tomei is rumoured to be playing Aunt May in the new Spider-Man film? Finding Aunt May unbelievably hot is gonna be weird."

Ben Shapiro added, "Marisa Tomei to play Aunt May in new Spiderman reboot. Gonna be so awkward when Aunt May is way hotter than Mary Jane."

But there are other supporters as well in the casting of Marissa Tomei as Aunt May in the "Spider-Man" reboot.

Twitter user Blue Coyote wrote, "Aunt May was usually too old in the comics to be Peter's real aunt (Great-Aunt, yes). Marisa Tomei would be the right age in reality."

Alex Welch added, "Marisa Tomei as Aunt May? Yes. Freaking. Please. Definition of perfect casting."

But Marissa Tomei as Aunt May in "Spider-Man" reboot isn't as surprising considering the different versions.

The Guardian noted that May Parker wasn't always old in the comics even if that character, along with geriatric Uncle Ben, was the first thing that comes to mind.

"Various comic book and television Spider-Man stories have made Aunt May a younger, more active participant in Peter Parker's adventures. In the Ultimate Marvel version, she is a strong and independent woman in her late forties or early fifties," it said.
