Citadel: Ahead of its premiere, Prime Video renews Priyanka Chopra and Richard Madden's series for a second season

There will be a second season of Citadel, the expensive and troubled drama from the Russo brothers that has been in development since 2018.

The Hollywood Reporter has learned from sources that the show starring Richard Madden and Priyanka Chopra Jonas has been picked up for a second season before its April 28 premiere. It's uncertain how many episodes season two will have; the rookie run will consist of a measly six episodes. The announcement came after the series' keynote speech and first clip were shown at South by Southwest this month.

Insiders say that the details haven't been worked out yet, so Amazon and representatives for the Russos' AGBO didn't want to say anything.

In mid-2018, Jennifer Salke, president of Amazon Studios, first talked about ideas for the large-scale, multi-layered, worldwide event series. Citadel, which Avengers directors Joe and Anthony Russo created, has an Indian adaptation already in the works. Amazon thinks that the spy drama will become a key, fully-owned brand for the streaming service.

Citadel is a make-or-break moment for the executive, who added MGM to her remit earlier this year. Salke's predecessors approved Lord of the Rings: The Rings of Power, but Citadel is a make-or-break moment for her.

The Hollywood Reporter said in September last year that Citadel's budget has gone up to more than $200 million because there have been so many reshoots since the show's creative team split in two over creative differences. The Rings of Power is now the most costly series to have ever been produced, with the current run of the series coming in second.

The Russos hired David Weil, the creator of Amazon's recently concluded drama Hunters, to take over the show, provide a more realistic perspective, and oversee $75 million in reshoots on a budget that was already planned at $160 million. Citadel also fired showrunner, Josh Appelbaum and director Brian Kirk.

Sources say that Weil will still be in charge of the second season, and the Russo brothers are likely to direct many episodes.

During SXSW, Priyanka disclosed that Citadel was the first time in her two-decade career that she had gotten pay parity.
