Ghosts Season 3 is back with more hilariously spooky goings-on. Yep, the hugely popular comedy — starring many of the actors from children’s hit show Horrible Histories — has returned for more chaos at Button House.

The show has proved so successful it was even given a Christmas special last year, which is normally the signal that a comedy has truly arrived.

Kiell Smith-Bynoe, who plays Mike, tells us his character has a lot more involvement with the ghosts this time.

“We’ll see some jealousy from Mike about him not being able to hang out with them. We get a lot more in this series of me with the ghosts, even though I can't talk to them directly. It was enjoyable filming that. It's usually the ghosts interacting with Alison. Mike's definitely learning to live with them. Before, it was an annoyance, and he was scared of them, so it has been a journey.” 

Here’s everything we know so far about the new series

Ghosts Season 3 release date

Ghosts season 3 started on 9 August on BBC1 at 8.30 pm. All the episodes are now available to watch on iPlayer.

Meanwhile, Mike is more intent than ever to put Button House on the map while trying to hold onto his day job."

After Alison messages her sister Lucy in an attempt to rekindle their relationship after the incident, she and Kitty fall onto the topic of Kitty’s own sister, who she talks about often. The other ghosts quickly shut down Alison’s question and manage to distract Kitty by saying there’s a balloon upstairs.

The ghosts explain that Kitty’s sister was horrible and if she ever found out the truth she would be heartbroken. However, Alison is adamant that Kitty should talk about it and that it could make her feel better.

Meanwhile, Mike’s desires to see the ghosts grow stronger and he begins researching ways on how to see them, which comes up with surprising results.
