Only Murders in the Building (Disney+) is the most fun you can have in your living room. Honestly. And who cares about the whodunnit? You find out at the end, so just sit back and enjoy the entertainment on show.

It’s funnier than any sitcom right now. This is the fourth season of this show, which is based in a New York apartment block, the Arconia, where residents, Charles (Steve Martin), Oliver (Martin Short) and Mabel (Selena Gomez) solve a crime for a podcast. Sounds fanciful, but this main cast can sell anything, and the guest stars are just as good if not better.

Admittedly, it’s boxes within boxes, but again that’s part of the fun, too. This time, while Charles worried about his body-double Sazz, they were whisked off to Hollywood , where producers at Paramount wanted to make a film of the podcast. Cue a well-drawn parody of what this daft process could be like, with sycophantic studio staff throwing themselves at the trio, two of whom are has-beens who can’t believe their luck.

Oh, and Meryl Street pops in again as Oliver’s love interest. Things look shaky. With guest stars Eva Longoria and Eugene Levy acting a version of themselves, it was hard to know where to look at a Hollywood party thrown in their honour.

Some may be asking: which is the daftest? Only Murders, or Hollywood ? I think Levy (Murtagh reunited with Cheaper by the Dozen’s star Steve Martin) answered that, with his gag, “Do you know what everyone’s got now -- sepsis!” Why did I laugh .
