Locomotive For Murder - The Improvised Whodunnit

If you are looking for something a bit different to do in Brighton this May, there is a show coming to the Brighton Open Air Theatre that relies entirely on what the audience brings to the table. It is called Locomotive For Murder: The Improvised Whodunnit, and it is essentially a murder mystery play where the script is written on the spot. The premise is straightforward: four characters board a train, and by the end of the journey, not everyone is left standing. A detective has to figure out who the killer is, but the twist is that the actor playing the murderer is the only one who knows their identity until the very end.

Because the show is produced by the team at Pinch Punch Improv, the entire performance is built around suggestions from the crowd. This means that every single night is different, as the plot develops based on the specific ideas thrown out by the people in the seats. It is a structured format, but the unpredictability is the main draw. The show runs for about 105 minutes, including an interval, so it is a decent chunk of time to spend in the theatre. It is worth noting that the content includes comedic murder scenes, some violence, and occasional strong language, so it is generally recommended for anyone aged 10 and up. They do have a 'Babes in Arms' policy, which allows children under two to attend for free if they sit on a guardian's lap.

For those planning to head down to the Brighton Open Air Theatre on May 9th, 2026, tickets are priced at £17 for standard entry, with a concession rate of £15.50 available. It is a good idea to book ahead if you are interested, as these types of improvised shows tend to have a specific capacity. It is a fairly relaxed way to spend an evening, especially if you enjoy theatre that doesn't take itself too seriously and involves a bit of audience participation. Whether you are a fan of classic whodunnits or just want to see how a group of actors handles the pressure of improvising a full mystery, this is the setup for the night.
