Amid all of the new elements introduced in the first trailer for the "Ghostbusters" reboot is at least one familiar face: Slimer, the fan-favorite little green ghost from the original films.

Sure, it's only a brief cameo, but he's there, at about the 1:34 mark.

Of course, that's definitely not the last we'll see of Slimer. Michael K. Williams revealed just last week that he shares screen time with the creature, providing the first actual confirmation that ol' Onionhead appears in the film. Whether he'll once again be the first ghost successfully captured by the Ghostbusters remains to be seen.

Directed by Paul Feig, "Ghostbusters" stars Kristen Wiig, Kate McKinnon, Melissa McCarthy and Leslie Jones. The film opens July 15.
