On May 21, 2010, Dan J Kroll from Soapcentral.com reported that actor Scott Clifton had joined the cast of The Bold and the Beautiful in the newly created role of Liam Cooper.^[1] Clifton was cast two months after leaving rival soap opera One Life to Live.^[1] The actor was initially unaware of who the character was when he auditioned for the role.^[2] On his first day on set, Clifton was told that his character would be called Liam. He then met with the executive producer Bradley Bell, who told him about Liam's backstory and that he would be Bill Spencer, Jr.'s (Don Diamont) long-lost son, which is why they decided to name him Liam, short for William.^[2] Clifton kept the information to himself, until it was revealed in the scripts.^[2] He filmed his first scenes on May 25, and made his screen debut as Liam on July 19, 2010.^[1]

Scott Clifton's job on The Bold and the Beautiful included withholding the secret of his character's paternity. Liam Cooper's introduction to viewers began with his quest to discover the true identity of his biological father, which potentially included several lead characters. Asked by the director if he wished to know the secret, or learn the truth when Liam does, Clifton agreed to hear the truth immediately. He withheld his knowledge from cast-mates and backstage crew for several months as the storyline played out.

At times, Clifton regretted that his character would not be the son of certain fathers. "Winsor [Harmon] played those scenes so subtly and sweetly, that even though I knew what was going to happen, I was watching Winsor thinking 'God, I wish I were his son.'" Yet, Clifton has praised the storyline and defended the choice of who ultimately became Liam's father, Bill Spencer, Jr., portrayed by Don Diamont. The fictional father/son duo have consistently clashed, which has led to greater storytelling potential.^[3]

An early plot hole was revealed to Clifton by fans of the show. Early on, Liam learns of the Forrester family after arriving in Los Angeles. But later it was revealed that he believed one of the Forresters could be his father even before he moved.^[3]

Of the character's unrevealed history, Clifton knows little. His interpretation of the character is that he is from the Midwest. He also believes that, while Liam's mother is dead, he has a living stepfather, who has yet to be introduced.^[3]

After the death of his mother, Liam relocates to Los Angeles to find his biological father. His only clue is that his father worked at the prestigious fashion house Forrester Creations. Liam finds employment as a computer technician at Spencer Publications. Liam later reveals that he could be Ridge Forrester's (Ronn Moss) son. Hope Logan (Kim Matula) takes pity on Liam and they become friends. Both Bill Spencer, Jr. (Don Diamont) and Thorne Forrester (Winsor Harmon) are revealed to have dated Kelly and could be Liam's father. While they wait for DNA results, Liam and Thorne form a bond. Liam learns Bill is his father and with Hope and Katie Logan's (Heather Tom) encouragement, they start to bond. Hope and Liam begin dating. Amber Moore (Adrienne Frantz) convinces Liam that they had sex and she is carrying his child. It soon emerges that Amber's mother, Tawny (Andrea Evans), faked the paternity test

During a feature on what storylines were working and not working for the show, a Soap World reporter quipped, "apologies to Team Liam fans, but he's such a wimp who wants to possess Hope despite his endlessly grating protestations of love for her. Quinn's right, he's a boy, not a man!"^[9] Helen Vnuk of TV Week included Liam in her feature on soap heroes, and she stated, "Ok, so Liam didn't save Ivy from an inferno or psycho killer. But, he did generously agree to marry her when she said she faced being deported to Australia. Any American who helps out an Aussie in trouble is a hero to us!"^[10]

In 2022, Charlie Mason from Soaps She Knows placed Liam at #8 on his ranked list of The Bold and the Beautiful’s Best of the Best Characters Ever, commenting that "Despite his (well-earned) reputation as a waffler, we couldn’t love Scott Clifton’s character any more than he does Hope.
