'an idealist dealing with his overbearing mother who crashes into the homes of his three ambitious sisters and, in succession, brings truth, happiness and a sunny disposition into their lives while also wreaking havoc'.
So I'm guessing a kind of Jack Lemmon 'buddy boy' from The Apartment but with family/domestic issues keeping him grounded rather than the career ladder in Wilder's classic? Count me in I suppose, but Rudd's dangerously becoming a member of the Jason Bateman school of "he plays the same damn role everytime". Jesse Peretz, who had an awful time with his Zach Braff comedy Fast Track (also known as The Ex) that earned $5 million worldwide just a year after it was being speculated as a potential high-revenue comedy is attached to direct based on a script his sister co-wrote. Filming will begin next month once the family roles are cast.
