Is The Authority movie still happening?

Last I remember, James Gunn said they were having some trouble adapting the Authority in a way that could fit with the DCU or something. So I think the project was in scriptwriting hell last I heard. Do we know if it's still that way or did it get cancelled? The characters can still appear seeing how Engineer was in Superman, though her personality was a tad bit different, probably to make her working with Lex make sense
