Mr Selfridge (ITV, 9pm)

THE latest series of Mr Selfridge has seen Harry (Jeremy Piven) suffer a dip in his fortunes, and with the pressure mounting, he's forced to come clean to Jimmy Dillon (Sacha Dhawan) about the extent of his financial problems.

However, Harry Selfridge's loss has been actor Sacha's gain, as he's thoroughly enjoying his part in the department store owner's downfall.

The actor says: "My character is an instigator in his dramatic decline so it's really exciting.

"You don't get to see many Indian actors in period dramas so I was really drawn to the fact that this series is set around the late 1920s, and it's such a brilliant area to explore. What's also amazing is that even though the character is Anglo-Indian he gets to sit on the big boys table with all the main characters and isn't just serving tea!

"Jimmy is a very suave and switched-on character, he instigates a lot of big changes that happen within Selfridge's and befriends the leading man in the show; I mean what is there not to enjoy and jump at the opportunity?"

And just in case he did need another incentive, there are always the clothes.

"The costumes that Jimmy wears are stunning and are tailor made for me, how amazing is that?

"I love taking on projects that flip the last job I worked on its head. My last character was a drug addict who never washed his suits, was very dirty and never turned up for work and now I'm playing a really clean cut, sharp and very clever character, it's so fun."

But while the role may be enjoyable for Sacha, his character does have a dangerous side.

"Jimmy loves the buzz of quick deals, making money as fast as he can and moving onto the next venture. It's a very dangerous way of operating but exciting, it can only lead to disaster and he's not just risking his own capital."

So, it seems Harry should definitely think carefully when a supportive Jimmy advises him to wipe out his debts by selling off the most valuable provincial stores, especially as it could further damage his relationship with his son Gordon.

However, with D'Ancona piling on the pressure and Lord Wynnstay's newspaper publishing a gossip story claiming that the recent assault on the store is linked to Harry's debts, it seems there may not be any other option. At least the Dolly Sisters won't be able to add to the businessman's financial problems, as for once Harry fails to succumb to their charms when they confront him about having their in-store credit cut off.

May and Victor, Amada Abbington and Tom Goodman-Hill, have rekindled their old romance and it finally looks like the pair are going to find some future happiness... as long as they don't rely on Harry to keep the wedding costs under control.

AC/DC and the Story of Aussie Rock (BBC4, 10pm)

DOCUMENTARY about the rock band, looking at how family-run Australian company Albert Music launched them onto the global music scene in the mid-1970s. The film reveals how independent record producer Ted Albert backed AC/DC for many years when their type of music and fashion seemed completely at odds with a UK and US scene dominated by punk, and examines the band's international breakthrough with 1979's Highway to Hell, and how they coped with the death of singer Bon Scott in 1980.
