'Reacher' star Sonya Cassidy joins Star Trek audio drama as Dr Rosalind Lear

Sonya Cassidy, known for her role in Reacher season 3, is set to join the Star Trek franchise in a new audio drama titled Star Trek: Khan.

The announcement was made at San Diego Comic-Con 2025, where it was confirmed that Cassidy will voice the character Dr Rosalind Lear, a historian who uncovers the lost logs of the character Khan Noonien Singh.

The series, which will be available on major podcast platforms, marks a departure from visual storytelling and will instead use a scripted audio format. The character of Khan will be voiced by Naveen Andrews, widely recognised for his work on Lost.

Star Trek: Khan is set before the events of Star Trek II: The Wrath of Khan, focusing on Khan’s period of exile. The story is original and not an adaptation of previously released Star Trek content.

The series will launch on September 8 2025, aligning with Star Trek Day, which commemorates the original series’ first broadcast in 1966.

A trailer was also released, offering illustrated visuals of the characters, as the format does not include live-action performances.
