Sam Ryder has received widespread critical acclaim for his portrayal of Jesus in Andrew Lloyd Webber's rock opera, "Jesus Christ Superstar." Following the musical's press night at the London Palladium, critics described Ryder's performance as "sensational and soul-stirring," marking a significant step beyond his Eurovision fame.

Ryder stars as the titular religious leader alongside Tyrone Huntley as Judas and Desmonda Cathabel as Mary Magdalene. Jesse Tyler Ferguson also takes on the role of King Herod, with other stars slated to alternate the part during the production's run. Due to popular demand, the show will transfer to London's Theatre Royal Drury Lane for a 12-week engagement in October, and Ryder is scheduled to continue in the role for a national tour next year.

Reviewers noted Ryder's strong vocal performance, particularly in the song "Gethsemane." The Times awarded the show three stars, with critic Dominic Maxwell highlighting Ryder's "charismatic best when in full song," calling his "Gethsemane" a "sensational, a one-man rock opera that prompts an in-show standing ovation." However, Maxwell also observed that Ryder appeared "wooden when having to silently find his place among the ensemble." The Telegraph gave the production five stars, with Dominic Cavendish praising Ryder's performance, stating that the show achieves a "blistering pay-off in the climactic title number." Olivia Garrett of Radio Times also awarded five stars, noting a standing ovation for Ryder's rendition of "Gethsemane" and expressing hope that "this is just the start of his musical career."

Patrick Marmion of the Daily Mail gave the show four stars, writing that Ryder's Jesus was "a little meek and mild" initially, but he delivered a powerful performance in "Gethsemane." Marianka Swain for londontheatre.co.uk also awarded five stars, commending Ryder's ability to convey the anxiety of the character and his "astonishing falsetto," though suggesting clearer lyric articulation. Alice Saville in The Independent gave four stars, acknowledging Ryder's vocal talent but noting a lack of acting experience in portraying the figure's inner struggles.

Ryder first gained national recognition as the runner-up in the 2022 Eurovision Song Contest. He subsequently performed at The Queen's Platinum Jubilee concert and released a chart-topping album. He has previously spoken about his struggles with depression following his Eurovision stint.
