Michael Keaton Breaks Out His 'Batman' Voice For 'SNL' Promo

Michael Keaton takes us back to Gotham City as he dusts off his gravely Batman voice in a new promo for "Saturday Night Live."

The Oscar-nominated star of "Birdman" makes his third appearance as "SNL" host this weekend, with musical guest musical guest Carly Rae Jepsen, who appears with him in the TV spots.

While "I'm Batman" was certainly expected -- if there's not a "Batman"/"Birdman" mashup on Saturday's show, we'll be severely disappointed -- it's unlikely anyone was counting on the reference to Keaton's largely forgotten 1996 comedy "Multiplicity."
