Jack Callahan is a fictional character from the Australian soap opera Neighbours, played by Andrew Morley.

The character departed on 30 March 2018, but Morley later reprised the role and returned on 26 February 2020, as part of the show's 35th anniversary celebrations.

Morley described the character as one with a "clean slate" due to his amnesia and lack of family ties or connections to Erinsborough.

His storylines have also focused on his rivalry with Mark Brennan (Scott McGregor) despite Morley stating that Jack has a lot of respect for him and feels that he is a good role model for his son.

Katie Baillie from Metro UK showed her compassion for Jack but later felt that he didn't act like an adult when he gets into a fight with Mark.

On 31 January 2016, Holly Byrnes from The Daily Telegraph announced the former Home and Away star Andrew Morley's casting on Neighbours as John Doe.

[1][2] Morley was asked to film an audition tape after he had received an email from his manager whilst in Cambodia helping raise money and awareness towards human trafficking.

[1] Morley commented on working with Paige Smith actress Olympia Valance describing her as "extremely friendly" and of a "great energy".

"[7] He later remembers that he is a Catholic Priest and goes to the police station to inform them of his past and his true identity is confirmed as Father Jack Callahan.

[4][5] Jack is described to be a "man of God" and to have "devoted his life to religion and helping people", with being a "genuine, kind, sincere and loving person".

[8] Paige falls for John and the feeling is mutual, with Morley describing it as "true love for both of them" and that "Jack has never felt like this about anybody.

[11] With Paige feeling upset about Jack's decision, she confesses to her mother, Lauren Carpenter (Kate Kendall), that she is unable to think straight around him, vowing to keep her distance.

[22] Paige goes back to where the baby is conceived and goes into labour and gives birth to a son, Gabriel Smith (Kian Bafekrpour).

It was hard playing the Steph and Jack relationship because it didn’t have the substance he had with Paige, so naturally the audience isn't going to believe in it as much.

[28] However, Steph talks to her friend Toadfish Rebecchi (Ryan Moloney) about her concerns, feeling the age difference between herself and Jack may be too big.

[29][deprecated source] On 5 February 2018, Daniel Kilkelly from Digital Spy reported that Jack and Paige would have a one-night stand.

[30] Kilkelly also reported that Steph would seek revenge when she finds out about the affair with her ransacking Jack's room at the backpackers in a fit of anger but later confesses to the police of her actions.

This brings repercussions for Steph as her planned trip for visiting her son in Fiji is ruined as her overseas visa is revoked due to the criminal charges for the damage.

[31] On 13 November 2017, it was reported by Kilkelly (Digital Spy) that Jack would "drive" Paige and Mark's relationship apart when he discovers that the pair are arguing.

With Elly Conway (Jodi Anasta) and Amy Williams (Zoe Cramond) determined to get Jack and Mark on better terms, they decide to get them together with a game of Croquet.

[38] After seeing how much Mark is struggling with their relationship, Paige and Jack decide to leave Erinsborough for a fresh start in Queensland with their son.

John's memory returns and he is able to tell Mark that Julie Quill (Gail Easdale) and Jacka Hills (Brad McMurray) caused the explosion.

He explains that he was questioning his faith when he came to Erinsborough and was staying with a priest in Elliot Park, but when he went away to Rome, Jack was left to counsel Julie at the church.

Jack looks after a little girl named Poppy Jarvis, who has cystic fibrosis, whilst her mother is in hospital, and he organises a fancy dress party for her.

Jack supports Steph when she thinks she is having a mental health relapse, and when she turns her motel into a cancer wellness centre.

Although Gabe is later found and returned by Cassius Grady (Joe Davidson), Jack is still steamed with Mark, resulting in a brawl with him during a day out.

Two years later, Paige returns to Erinsborough and informs her former stepmother Terese Willis (Rebekah Elmaloglou) that she believes Jack is having an affair.

Upon discovering that there is a vacancy at a parish church in Adelaide, where Mark is living, he offers to move there so Paige and Gabe can do so as well.

Near to his first appearance, while his identity remained unknown, critics were not sure what to make of the character, with Digital Spy's Kilkelly describing him as "mysterious"[3] and Sam Warner commenting: "it's unclear if he is a hero or villain".

As IF that's even a consideration for a twenty-something guy when faced with Olympia Valance diving semi-naked into a backyard pool (yes, this really happens in this episode.
