Proof Married At First Sight groom Ryan Donnelly is a paid actor as he is spotted on the set of horror movie Send Help starring Rachael McAdams and Dylan O'Brien

Married at First Sight groom Ryan Donnelly appears to have taken up work as a paid actor after completing his controversial stint on the reality hit.

The 36-year-old was spotted on the streets of Sydney on Thursday filming the new US-made film Send Help, which features Hollywood stars Rachel McAdams and Dylan O'Brien.

Ryan, who is matched with business woman Jacqui Burfoot on MAFS, was seen strutting his stuff dressed as a 'corporate type' in a smart blue suit, white shirt and tie.

Sporting a fresh slick haircut and a clean shaven look for his part as an extra, Ryan's completed his look with shiny black shoes and a designer carry bag.

Between filming scenes Ryan was seen carrying a zip garment bag over his shoulder and conversing with a member of the film crew. 

Also spotted filming on Sydney streets last week for the upcoming horror film was Dylan O'Brien.

The 33-year-old Maze Runner star was seen on Wednesday going over the location with a crew member wearing a blue shirt, trousers and carrying script pages.

'24' star Dennis Haysbert was also on set and appeared to be in costume, dressed in a grey suit and matching sweater.

Also seen on set the same day was Australian actor Xavier Samuel.

The Twilight actor, 41, also appeared to be dressed as a businessman for his role in the new film, in a costume that featured a white shirt, bold tie and suspenders.

Meanwhile, little was known about Ryan's acting ambitions before joining the cast of MAFS, where he was known as a 'project manager'.

Ahead of appearing on the experiment he had shared pictures to his social media dressed as a NSW police officer for a small acting role on the set of a TV series. 

Soon after Daily Mail Australia confirmed last September that Ryan was joining MAFS, the aspiring actor deactivated his StarNow and TheRightFit profiles - influencer and acting casting sites.

Friends describe him as a 'super nice guy', who is unlucky in the love department and say he is 'tired of all the dating apps'.

He is also super passionate about maintaining an active lifestyle and is a personal trainer.

Ryan is the third actor and influencer to be confirmed for the series alongside Paul Antoine, who appeared on The Real Love Boat, and Bachelor star Sierah Swepstone.

His confrontational and tear-filled match with Jacqui had had armchair critics claiming that the pair were 'acting' as a way to launch screen careers.

'Ok so are these two actors?,' moaned one Instagram user after watching the pair clash on tuesday's ranking challenge.

They continued: 'Very bad acting. Has to be fake so scripted.'

'I am convinced she’s an actress,' exclaimed another user after watching Jacqui burst into tears.

'Absolutely believe they are both actors, trying to get recognised by Home and Away,' posed another on the same thread. 

It comes after Ryan was left fuming during Wednesday night's episode, after his wife Jacqui Burfoot read him a shocking 'confession letter'.

The confronting episode saw Jacqui, 31, read a heartfelt letter out to Ryan, in which she described the very high standards she has when searching for a partner.

However, despite Jacqui's claim that the letter was meant to help Ryan better understand her, he took it as a personal attack on who he was.

'I'm hoping off the back of this [letter], Ryan will step up his game a bit and bring something interesting to the table,' Jacqui told the cameras before visiting her partner.

'I'm a very curious and intelligent person. My mind is the thing I love most about myself - but unfortunately, most people judge a book by its cover,' Jacqui read to Ryan.

'They are incapable of believing there is no inverse correlation between looks and brains. You can be a beauty queen and still have a brain,' the good-looking law graduate added.

She continued reading and began to describe her many achievements - and why a potential partner needed to bring something special to the table to meet her standards.

Still, Ryan was not impressed by Jacqui's letter and later told the cameras her speech made him very uncomfortable.

'It just seemed like she was grandstanding. It was quite condescending and patronising. It was like she was saying, "Can you match me?"' he began.

'Or, "This is the level of man I need", like she was trying to illustrate it is a failure in our current scenario or I am failing her. I feel insulted.'

The NSW-based project manager said he was disappointed Jacqui only spoke of assets and material wealth as things that were important to her, rather than her personal hopes and emotions.
