The 31-year-old actor from The Hour on filming a Thai boxing thriller in Bangkok

I know him. He was on that Mad Men knock-off last week. Look, The Hour is nothing like Mad Men – that's our final word on the matter. But you're right, he did pop up as the dashing Bill Kendall.

Was it me or did my TV crackle with sexual tension during his scene with Bel (Romola Garai)? No, ours did that, too.

So we might be seeing more of Bill Kendall from here on? No spoilers, but it's a safe bet. And it might be a while before we work out if he's a good egg or a bit of a cad.

What else has Tom been in? Apart from Brit gore-flick Donkey Punch (oops!) he's mostly done classy theatre stuff at places like the Donmar Warehouse and the National Theatre. But look out for him...
