The train used in back to the future 3 was the same train that was used in the tv show petticoat junction.
The Batgirl film was scrapped by WB for taxes break purposes.
You can’t legally watch Infinity Train for the same reason.
From the deep Final Space shaped hole in my heart, fuck WB/ Discovery.
I’m of the opinion that claiming media for tax breaks should immediately forfeit IP/ copyright protections and require it to be made available to the public.
There is a Final Space graphic novel coming out that should wrap up the plot!
