World of Reel‘s Jordan Ruimy, having read the same tweet and the same Variety story that everyone else had, did actively speculate about a new David Lynch film going to Cannes, and he did exhibit a certain enthusiasm for same. But he was never more than a go-between.
The guy who actually started the rumor with a single tweet (way back on April 6th) was Kaleen Aftab.
But things really took off on 4.11 (three days ago) when Variety‘s Elsa Keslassy reported the following: “Most surprisingly, according to two well-informed sources, there will even be a David Lynch feature film which has been completely off the radar and stars Laura Dern — either as a cameo or a supporting role — along with some other Lynch regulars.”
So if you want to punish someone for running dicey info, punish Aftab and Keslassy. Ruimy did nothing.
