Just yesterday a bunch of new photos introduced us to several of the characters from Finding Dory, including some totally cute sea otters (seriously) and a pair of sea lions voiced by Idris Elba and Dominic West (The Wire reunion!). But Pixar’s long-awaited sequel to Finding Nemo isn’t done casting (no pun intended) up yet, as former SNL star Bill Hader and current SNL star Kate McKinnon have joined the lineup.

Disney and Pixar’s official cast announcement includes all the new characters debuted yesterday, as well as the addition of Hader and McKinnon as “a fish couple that Dory briefly encounters along the way.” And by “briefly” they mean a cameo appearance, unfortunately. Director Andrew Stanton has also promised other cameos from Finding Nemo characters, along with the promise of a special post-credits scene.

Finding Dory welcomes back Ellen DeGeneres as the titular forgetful fish and Albert Brooks as Marlin. The official synopsis offers additional details:

“Finding Dory” welcomes back to the big screen everyone’s favorite forgetful blue tang Dory (voice of Ellen DeGeneres), who’s living happily in the reef with Marlin (voice of Albert Brooks) and Nemo (voice of Hayden Rolence). When Dory suddenly remembers that she has a family out there who may be looking for her, the trio takes off on a life-changing adventure across the ocean to California’s prestigious Marine Life Institute, a rehabilitation center and aquarium. In an effort to find her mom (voice of Diane Keaton) and dad (voice of Eugene Levy), Dory enlists the help of three of the MLI’s most intriguing residents: Hank (voice of Ed O’Neill), a cantankerous octopus who frequently gives employees the slip; Bailey (voice of Ty Burrell), a beluga whale who is convinced his biological sonar skills are on the fritz; and Destiny (voice of Kaitlin Olson), a nearsighted whale shark. Deftly navigating the complex inner workings of the MLI, Dory and her friends discover the magic within their flaws, friendships and family.

Not mentioned above are Elba and West’s roles as sea lions Fluke and Rudder, a couple of lazy former residents at the Marine Life Institute who spend their time fighting over a rock outside the center. Stanton says the characters were inspired by the gangsters in Guy Ritchie films.

Finding Dory hits theaters on June 17.
