`Fantastic Four` back at Marvel, planned for 2020 release?

Washington D.C.: If sources are to be believed, then Fox has given its rights of the `Fantastic Four` back to Marvel Studios.

Reports have claimed that the film will be released in 2020, taking up one of the three as-yet-untitled movies Marvel has planned, The Independent reports.

Earlier this year, Fox released `Fantastic Four,` which turned out to be a flop at the box office, making the company unsure of whether to green light a sequel or not.
