EXCLUSIVE: We hear that Doctor Who actor and 1995 Oscar winner Peter Capaldi is boarding James Gunn’s The Suicide Squad at Warner Bros. We also hear that Saturday Night Live‘s Pete Davidson has been in talks for a small cameo in the pic, and there’s a chance he’ll do it during breaks from SNL. That deal still is coming together.

Word is that there’s a table reading for the DC sequel on September 11 with production starting 12 days later at Pinewood Studios in Atlanta for an August 6, 2021, release.

No details were given about the roles for Capaldi or Davidson.

The Suicide Squad cast so far includes Margot Robbie (Harley Quinn), Viola Davis (Amanda Waller), Jai Courtney (Captain Boomerang), Joel Kinnaman (Rick Flag) as well as new castmembers Idris Elba, David Dastmalchian (Polka-Dot Man), Daniela Melchior (Ratcatcher), Flula Borg, Steve Agee (King Shark, which Deadline reported exclusively Monday), Nathan Fillion and Taika Waititi. Gunn wrote the script to The Suicide Squad. Chuck Roven and Peter Safran are producing. EP is Nik Korda.

The Oscar- and BAFTA-winning Scotland native Capaldi, who is repped by Paradigm and Troika, won both trophies for directing and writing the live-action short Franz Kafka’s It’s a Wonderful Life, which starred Richard E. Grant. Capaldi also directed nine episodes of BBC’s Getting On, which ultimately was adapted into a U.S. edition for HBO. His credits include Bill Forsyth’s Local Hero, BBC’s TV series The Thick of It (for which he won a BAFTA for comedy series lead actor), World War Z, Paddington 2, Christopher Robin and ITV/Netflix’s animated series Watership Down.

Davidson joined Saturday Night Live in September 2014. He recently starred and co-wrote his star vehicle for Universal, which Judd Apatow directed and produced. The pic opens on June 19. Davidson also appeared in Netflix’s Mötley Crüe biopic The Dirt and Big Time Adolescence, which made its world premiere at Sundance. He’s also the voice of Jerry in Sony’s The Angry Birds Movie 2, and stars in Jon Turturro’s upcoming Big Lebowski spinoff The Jesus Rolls. Davidson is repped by ICM, Brillstein Entertainment and Gray Krauss Sandler Des Rochers.
