The 69-year-old son of Dad's Army star Arnold Ridley said his father would have 'advised against' his great grand-niece Daisy Ridley pursuing an acting career.
Nicolas Ridley, a teacher from Bath, said his father - famous for playing the doddery Private Charles Godfrey in the much-loved BBC comedy - would be 'delighted' to see his relative follow in his acting footsteps although he may have encouraged her to not work in such a 'tough' discipline.
Twenty-three-year-old Daisy, Arnold's cousin once removed, plays Rey in the box office smash hit, Star Wars: The Force Awakens.

Arnold Ridley's son Nicolas said playing the doddery Private Charles Godfrey in Dad's Army gave his father his 'confidence back' after the horror of the conflict, pictured left during the war and right in the show
Speaking to Daily Mirror, Nicolas said: 'If Daisy had asked my father about a career on the stage, I think he might have advised against it because he knew how tough it could be.
'But he would have been delighted to see her enjoying such richly deserved success.'
Hollywood starlet Daisy, who grew up in London, has previously spoken about how Arnold helped influence her career. She told Entertainment Weekly: 'My great uncle was in Dad’s Army.
'They’re redoing it as a film. Michael Gambon, who played Dumbledore [in the Harry Potter movies], is playing who my great uncle played. Both my parents are creative. My dad did act when he was younger, but they’re both very creative.'

The programme offered much-needed respite for Arnold during the late 1960s and 1970s.
He was the only member of the cast to have served in both world wars, as well as signing up for the Home Guard.
Nicolas said that the show helped his father deal with 'financial anxiety' and his 'lost confidence'.
He said: 'I'm immensely grateful to David Croft [programme creator] for taking the risk of casting a very frail, old man who everybody else thought would die by the end of the series.'
Arnold volunteered for the Army in 1914 at the age of 18 but was rejected because he had a broken toe.
He was accepted a year later to the 6th Somerset Light Infantry and posted to France.
Within days of arriving at his base he was hit by shrapnel and shot through the thigh.
Arnold later returned to the front from convalescence only to be sent over the top twice during the Battle of Somme in 1916.
During a second attack, at Gueudecourt, now as a Lance Corporal, Arnold's battalion tried to push back enemy troops with bayonets and bombs.
He was knocked to the ground by a rifle blow to the head.
Arnold was lunged at by a German soldier carrying a bayonet, which sliced into his groin. A second blow pierced his left hand and wrist.
Arnold came round in a field hospital but it took 15 operations to save his hand.
Writing about his experiences at the time, Arnold said: 'I always remember my disappointment the next morning when I found my hand was still on.

‘I hoped I’d been maimed for life because I knew that they couldn’t send me back. I was 20 then, and it’s not a right thought for a young man to hope he’s been maimed for life.'
He was classed as an invalid and discharged on medical grounds before joining the Home Guard.
Reflecting on his father's life during the war, Nicolas previously told MailOnline: ‘He was angry and bitter for some time after the First World War and the horrors of trench warfare stayed with him all his life.
‘But a mark of his great courage was that he found a way to deal with an awful lot of it. He survived, both mentally and morally, because he was a thoroughly kind, gentle, decent man.’
Arnold suffered horrific nightmares and regularly woke drenched in sweat for many years after the war. If he was disturbed, his first instinct was to attack.
Nicolas said his father was 'terrified' he would 'black out on stage' but he went to star in a number of hit shows, Arnold pictured far right
Dad's Army ran for nine series from July 1968 to November 1977 and is still aired on the BBC
Nicolas recalled an incident as a child when he was throttled by his father. He said: 'He needed his afternoon sleep and I remember, as a child of five or six, waking him up suddenly.
'He instantly had his hands round my throat. It was a most appalling moment for both of us.
‘We could never wake him suddenly because he’d go straight into “trench mode’’, even in his 80s.
‘We would have to knock on the sitting room door first and warn him that we were coming in. The involuntary reactions were still there.’
