Stan Lee's daughter alongside Sony in spitting Spider-Man with Disney

While many fans have rallied to Disney after the rumor that discussions have taken place between the company and Sony on future Spider-Man movies, at least one person stands behind Sony: the daughter of Stan Lee.

Joan Lee, in a statement to TMZ, said that Marvel and Disney should be "controlled and balanced" in the search for total control over his father's creations.

"Whether at Sony or at someone else's, the ongoing evolution of Stan's characters and legacy deserves multiple points of view," she said. While the legendary comics author Lee created the Spider-Man character for Marvel comics in the 1960s, Sony holds the rights to this film for about two decades.

Disney, owner of Marvel, and Sony have signed an agreement in 2015 that would allow Spider-Man to be part of the Marvel film universe. In the initial agreement between the two companies, Sony would allow Marvel's creative team to integrate Spider-Man into its film universe and assume 100% of production costs.

In exchange, Disney received 5% of the "first gross dollar," or 5% of ticket sales as of the first day of the release, and retained the character's marketing rights. Sony would collect the rest of the mail at the box office.

Disney would have proposed a 50/50 co-financing agreement, which means that each company would cover half of the production costs and then distribute the profits, according to the entertainment website, Deadline. Sony would have refused.

If discussions do not resume, it is likely that Spider-Man will no longer be part of the Marvel film universe, which could be detrimental to both Sony and Marvel.

Lee seemed to support Sony's decision not to accept this new co-financing agreement.

"When my father died, no Marvel or Disney person contacted me," Lee said. "Since the first day, they have trivialized my father's work and never showed him respect or decency.In the end, no one could have treated my father worse than the Marvel and Disney. "

Disney representatives did not immediately respond to CNBC's request for comment.
