They really need to do a First Avenger/Cold in July riff with Frank. Set the next film in the early 80's. Make Frank a Vietnam vet. Make his adversaries challenging, intelligent, and formidable. Not cartoony. Hell, hire Jim Mickle to direct it. That guy seems like he would understand exactly what to do with Frank.
On the subject of Lexi, I really think she is capable of making something cool. She will hopefully get to have that moment where she connects with a script and it resonates for her. I think GSH was close, it's a good film, and maybe that's the film she will be remembered for. PWZ will not be, at least not for me.
It's funny, I have not read the Sutter script but I remember Tom and even Sutter mentioning how much they hated it. When the guy who wrote it pipes in and says it was shit, then it really must have been Sutter wiping his ass with the character and cashing a check.
The interview was worth a listen though, thanks for the link.
