At the rate they're going, filmmakers will have no spoilers left for movie fans once Suicide Squad – the supervillain movie featuring Joker (Jared Leto), Harley Quinn (Margot Robbie), Deadshot (Will Smith) and more – hits screens next summer.

After taking over Toronto’s Yonge Street for three nights this week for a chase scene involving the Clown Prince of Crime, director David Ayer (Fury, End of Watch) brought out the Batman early Thursday morning.

In what is likely to be a pivotal scene in the film, the Caped Crusader was seen clinging to the roof of Joker’s fuchsia Lamborghini.

Batman’s appearance has been rumoured since the DC Comics film starting shooting in Toronto last month (Ben Affleck, who plays the hero in next year’s Batman v Superman: Dawn of Justice has been spotted in the city).

Since filming began last month, Suicide Squad has shut down parts of Toronto’s financial district – for a helicopter crash and an action scene outside of the Trump Hotel – and parts of Bloor Street.

Another crash scene was staged on Yonge Street in early May.

Other stars appearing in Suicide Squad include Joel Kinnaman as Rick Flagg, Jai Courtney as Captain Boomerang, Cara Delevingne as Enchantress, Adewale Akinnuoye-Agbaje as Killer Croc, Adam Beach as Slipknot, Jay Hernandez as El Diablo and Karen Fukuhara as Katana. Viola Davis will also star as Amanda Waller.
