After a bye week, 'Saturday Night Live' is back this weekend with host Scarlett Johansson and musical guest Arcade Fire.

This marks Johansson's third time hosting the show, though she popped up last fall when her husband, Ryan Reynolds, made his hosting debut. Fingers crossed for a Reynolds cameo!

Meanwhile, watch today's just-released promos for Saturday's show to tide you over -- Johansson practices her accents with, gets ignored by, then gets directed by 'SNL' cast member Jason Sudekis.
