WATCH: Margot Robbie and Kate McKinnon rock out for SNL trailer

Saturday Night Live - or SNL - is something of an institution over in the US.

The late-night live television sketch and variety show created by Lorne Michaels back in 1975 has been entertaining the masses for over four decades, with a list of alumnus that reads like a who's who of comedy greats. Former stars include - *deep breath* - Dan Aykroyd, John Belushi, Chevy Chase, Jane Curtin, Bill Murray, Eddie Murphy, Billy Crystal, Nora Dunn, Amy Poehler, Chris Rock, Julia Louis-Dreyfus, Tracy Morgan, Andy Samberg and Kristen Wiig. And that's just to name a few. Season 42 kicks off this weekend with Margot Robbie making her hosting debut on Saturday's premiere. The star of The Wolf of Wall Street and Suicide Squad has appeared on the show before, as recently as May, but never fronted an episode. To celebrate the fact and look forward to the new season, Robbie and Ghostbusters star and SNL regular Kate McKinnon feature in a number of short trailers for Saturday's broadcast - and they make for an engaging duo. The snappy dialogue includes failed girl talk, election japery, and the pair rocking out to the 'pre-show' vibes.
