With Bridesmaids star Melissa McCarthy and Oscar-nominated Brit Jude Law, starring in new comedy movie Spy; Hollywood heart-throb Chris Pratt, talking about new blockbuster Jurassic World; top comic John Bishop; and music from Florence and the Machine.

This week Graham welcomes Hollywood heartthrob Chris Pratt, Bridesmaids star Melissa McCarthy, Oscar-nominated actor Jude Law, top comic John Bishop and British indie rock band Florence and the Machine.

Chris, talking about and demonstrating his perfect, if unlikely English accent, says, "When I was filming Guardians of the Galaxy in the UK we watched a lot of garbage TV and my wife went crazy for TOWIE. She fell in love with the show and I started picking up the accent so now the only British one I can do is an Essex one."

Asked about his new movie Jurassic World, he says, "I was 13 when the original film came out and I was swept up in it. I could never at that time have imagined that I could even be an actor let alone an actor who gets to join that franchise. I was captivated by the idea that it was real. I wasn't terrified, I was mesmerised." And on the new film he says, "It is legitimately really good, which is such a relief!"

Revealing he got into trouble with NBC while making Parks and Recreation, he says, "We were shooting a scene where my character turns up naked at my co-star's door. I was wearing skin coloured underwear and I wasn't getting quite the right reaction I was hoping for. It was late in the day so I decided to improvise and drop my trousers for the take. Her reaction was great and it's the take they used!

"Then I got a letter from NBC's HR department that said, 'There is a protocol about nude scenes. This is not a joke and you are being reprimanded and you can't go around telling people about this like some kind of joke!' I've framed the letter!"

Jude, talking about a nude bathing scene he had to do while appearing in Indiscretions on Broadway, recalls one particularly embarrassing night, "I had some friends in and because of that the crew filled the bath with ice. It was cruel. Everyone needed binoculars!"

Melissa, talking about her star on the Hollywood Walk of Fame, and asked if her parents were at the unveiling, she says, "Shockingly my dad was not there because he was de-weeding the lake. I said, 'I'm not going to get another one of these you know,' and he said, 'I know, but the weeds...' It was strange because he is normally embarrassingly supportive."

Revealing her audition for Bridesmaids didn't quite go to plan, she says, "I was reading a scene about me falling off a cruise ship and felt a bit too comfortable and started improvising. I told an eight-minute story about a sexual encounter with a dolphin. It went on for a very long time and I feel I went into some really weird black out. On the way home I said to myself, 'Why do you always get weird?' I was amazed to get the part!"

John, talking about his new TV show says, "If I never do anything else on telly again after this, I've done the show I've always wanted to do. It's a dream."

And, on receiving a Fellowship from Liverpool John Moores University, he says, "Never did I imagine someone would give me an award like that. It was a lovely moment and I felt like an advert for comprehensive education. I turned up and there were 700 students receiving doctorates and degrees that they had worked for it and I had done literally nothing. There was part of me that felt guilty for a moment."

Asked why he took a selfie on such an occasion, he says, "I hadn't prepared a speech because I thought I would just do a bit of stand-up but when I got there it didn't seem right so I took a photo instead!"
