Both outlets also mentioned in the same breath that a standalone Obi-Wan Kenobi film, which they reported being in development back in August, still doesn't have a writer attached.
As the outlet notes, a rumored Boba Fett movie from "X-Men" helmer Simon Kinberg was reportedly in the works, and it's unclear if this newly-revealed project from Mangold is different. The character has always been a fan favorite. It is the second A Star Wars Story film and the first to specifically focus on an Original Trilogy character in the title.
Despite his quiet nature, the mercenary became a favourite after he appeared in 1980's Empire Strikes Back as the man who brings Han Solo (frozen in carbonite) to crime lord Jabba the Hutt.
It'll be interesting to see what approach Mangold and Kinberg adopt if the solo outing comes to fruition.
Daniel Logan, the actor who played a child version of the bounty hunter in 2002's Attack of the Clones, is only 30 years old and is still acting. Han Solo was a safe choice, but there are 5 others in line behind him.
As for the idea of a Boba Fett movie: well, your mileage will certainly vary on whether or not that's a good thing. Before Logan, he directed The Wolverine in 2013. One suspects we'll get clarification on that in the very near future.
The George Lucas prequels showed Boba Fett's origin as a subplot but more importantly, his escapades were featured in various books, comics, animated series, video games and merchandizing. To avoid this trap, Mangold and his creative team need to dive into uncharted territory, giving the character fresh context and providing fans an unpredictable adventure.
