The folks at Lucasfilm are not known for giving away secrets lightly -- but at a recent Star Wars Celebration panel, "Star Wars: Rebels" executive producer Dave Filoni and Lucasfilm's Pablo Hidalgo did take the opportunity to reveal a small piece of Boba Fett's backstory through a rough, unfinished scene from the cancelled "Star Wars: The Clone Wars" animated series (via The Hollywood Reporter).

In the scene, which Filoni and Hidalgo showed to the attending audience, bounty hunter Cad Bane had captured a couple of Fett's friends, sparking a Sergio Leone-style stand-off of epic proportions between the two guns-for-hire. Then, in a heartbeat, the rivals both draw their blasters, each hitting the other and knocking their opponent to the floor.

Bane's shot is then shown to be the blast that left the iconic impact on Fett's headgear that's visible in both "The Empire Strike Back" and "Return of the Jedi." However, neither Filoni nor Hidalgo were willing to confirm whether or not Bane survived the encounter.

At the same panel, the pair also showed off some concept art from the upcoming season of "Rebels" in which the clone trooper "Rex" CT-7567 is seen sporting a green and tan camouflage jacket.

A number of fans suspect this is a playful reference to the fan-favorite theory that the white-bearded rebel -- seen in "Return of the Jedi," as part of the squad that was sent to disable the shield generator -- was actually an older version of Rex from the animated show.

Whether or not that means Rex survived all the way through to "The Last Jedi" is still up in the air...
