The actress, Joely Richardson, has spoken for the first time about the death of her actress sister Natasha.
Speaking in an interview with Tatler magazine, the 44-year-old said she threw herself into work, going back on set the day after Richardson's funeral.

She also remembered how close their relationship was despite being like "chalk and cheese" and described the shock she felt at her sister's untimely death.
She said: "We were such opposites. Chalk and cheese, but completely enmeshed in each other. I hadn't lived a day in my life without her.
"You worry about your children and your elders, but I never imagined such a thing as this. Tash was a given to me. The shock shatters you on a cellular level, and it takes time for the pieces to come back together, albeit in a different formation."
Joely completed filming 'The Day of the Triffids' for the BBC after her sister’s death followed by a trip to New York to finish 'Nip/Tuck' before moving on to play Catherine Parr in 'The Tudors'.
She said: "A strange autopilot kicks in; your psyche puts your work day into a different compartment from your private life. I'm not kidding - my first shot back on set was reacting to someone dying."
The actress also said she is going to New York with her 17-year-old daughter Daisy for two months to be closer to Natasha's sons, Micheal, 14, and Daniel, 13.
