I missed when Star Wars (from 1977 to 2005) were serious movies without irony that break the fourth wall.
In fact this one isn’t really breaking a fourth wall since Jar Jar is clearly gonna speak with Anakin. But the SE Boba in ANH is one of the very few instances where that happen. Plus the Tarzan reference in two movies. So yeah, it happened before, agreed. Not on the current magnitude though.
