Not only on European but also on “Hollywood stile” movies I worked on production sound dialog has a very high value. There are not much directors around that like to do ADR if they can avoid it. Because its hard und difficult work to get the performance from the actors in studio and a big risk of making the movie worse.
There are exeptions (directors, producers knowing that they have a big production sound problem (traffic sound in historical movie etc.) or in one single case I worked with a director that had the idea production sound being a bad compromise and wanted all dialog replaced (180 min)…But nobody normally has this sort of money.
I expect you will have to bring in good arguments for every single line you want to have replaced if your director doesnt like ADR. A general argument like "They do it on all big movies* will nor help…
