It's something gets thrown around a lot in film, TV and theatre. There's bad blood, good blood, mudbloods, blood thicker than water and blood brothers.

This episode we're talking about blood, and our guest this time is Rob Smith, blood master as well as an all-around effects bod. He also runs a lot of foam, and makes exquisite soft foam appliances which you really need to feel to appreciate.

He makes his own pieces but runs a lot of foam for other people, and you'll certainly have seen his work if you've been to the cinema in the last few years!
