Iron Man Memoir On Hold

Iron Man star Robert Downey Jr has postponed plans to write his memoirs.

He’s so sure he doesn’t want to put pen to paper just yet that he has even returned his advance to publisher HarperCollins.

No word yet as to why he wouldn't be writing the book, which was originally scheduled to come out this year, and had been billed as a "candid look at the highs and lows of his life and career."
