IS IT HARD BEING SO INTIMATE ONSCREEN?
Angels in America [the 2003 HBO movie] was such an intimidating experience that I have never felt that way again. Once you have had to break down in an AIDS fever two feet from Meryl Streep, nothing really seems that daunting. And luckily, I got along with Julianne's husband.
