In the series premiere of The Book of Boba Fett, Boba Fett is shown to be in some sort of recovery tank (similar to the one seen in Empire Strikes Back where Luke is recovering on Hoth). During this, he is shown to be dreaming about his past where multiple flashbacks are shown, two of which were:
Flashback # 1: Clash on Kamino (one image below). This was similar of Jango and Boba's escape from Tapoka city on Kamino right after a short fight between Boba and Obi-Wan Kenobi.
Flaskback # 2: Battle of Geonosis (one image below). This was similar to the scene from Attack of the Clones after Jango was beheaded by Mace Windu.
Both these flashbacks were reminiscent of specific scenes from Star Wars: Attack of the Clones. So, were the scenes from these flashbacks actually repurposed/reused from the prequels?
