On paper, “This Must be the Place” is an intriguing proposition: This Italian-French-Irish co-production marks the English-language debut of Neapolitan director Paolo Sorrentino, utilizes eclectic filming locations — including Dublin, New York and New Mexico — and stars two of the finest actors working today — Sean Penn and Frances McDormand. It’s a crushing shame therefore that this cosmopolitan picture is such a muddled disappointment.
