Sunkrish Bala (The Walking Dead) has booked a season-long arc on ABC drama series Castle. Bala will play Vikram Singh, a high-strung, tech analyst with a complicated past. Bala will next be seen in FX’s You’re The Worst. He’s repped by Greene & Associates and Pallas Management Group.

Anabelle Acosta (Ballers) is set for a multi-episode arc on ABC’s Quantico, the network’s new drama series that premieres September 27 at 10 PM. Acosta will play recruit Nathalie Vazquez, a former cop from Laredo, Texas. Driven, kick-ass, and fiercely competitive, she’s almost mercenary in her focus, more interested in always coming out on top than being a team player. The ABC Studios-produced Quantico revolves around a diverse group of recruits at the FBI Quantico Base, one of whom is suspected of masterminding the biggest attack on New York City since 9/11. Acosta is repped by CESD Talent Agency and Leverage.
