Following his heartbreaking exit from Casualty earlier this year,
BBC fans have gone wild after spotting
Derek Thompson in another drama series on the channel.
The actor, 75, shocked viewers when
he made an appearance on Belfast-based series Blue Lights on Monday evening for the second episode of the second series.
Charlie appeared towards the end of the episode as viewers flocked to X, formerly known as Twitter, to express their views on the legendary star’s surprise cameo on the show. One excited BBC viewer penned: “When you see Charlie from Casualty in #BlueLights,” alongside a meme of Leonardo DiCaprio pointing profusely from a Once Upon a Time in Hollywood scene.
