Morgan Freeman -- 284 Million Reasons to Reunite with Tom Cruise

Just two-and-a-half months after "Oblivion" was released to some not-exactly flattering reviews ... Morgan Freeman tells TMZ he's already trying to reunite with Tom Cruise ... and it's obvious why.

Despite an unimpressive 55% rating on Rotten Tomatoes, "Oblivion" reportedly raked in $284 MILLION at the box office ... on a $120 million production budget.

Translation -- Tom Cruise still puts butts in the seats ... even after "Rock of Ages."
