Peter Seamus Lorcan O'Toole (born 2 August 1932) is an Irish actor of stage and screen. O'Toole achieved stardom in 1962 playing T. E. Lawrence in Lawrence of Arabia, and then went on to become a highly-honoured film and stage actor. He has been nominated for eight Academy Awards, and holds the record for most competitive Academy Award acting nominations without a win. He has won four Golden Globes, a BAFTA, and an Emmy, and was the recipient of an Honorary Academy Award in 2003 for his body of work.

Peter Seamus Lorcan O'Toole was born in 1932. Some sources give his birthplace as Connemara, County Galway, Ireland, and others as Leeds, in the West Riding of Yorkshire, England, where he grew up. O'Toole himself is not certain of his birthplace or date, noting in his autobiography that, while he accepts 2 August as his birthdate, he has a birth certificate from each country, with the Irish one giving a June 1932 birthdate. O'Toole is the son of Constance Jane (née Ferguson), a Scottishnurse, and Patrick Joseph O'Toole, an Irish metal plater, football player and racecourse bookmaker. When O'Toole was one year old, his family began a five-year tour of major racecourse towns in Northern England. He was brought up Roman Catholic. O'Toole was evacuated from Leeds early in World War II and went to a Catholic school for seven or eight years, where he was "implored" to become right-handed. “I used to be scared stiff of the nuns: their whole denial of womanhood – the black dresses and the shaving of the hair – was so horrible, so terrifying,” he later commented. “Of course, that's all been stopped. They're sipping gin and tonic in the Dublin pubs now, and a couple of them flashed their pretty ankles at me just the other day.”

Milo Anthony Ventimiglia (born July 8, 1977) is an American actor best known for his role as Peter Petrelli on the NBC television series Heroes. Ventimiglia was first noticed by fans during his three year stint on the WB series Gilmore Girls, playing Rory Gilmore's love interest Jess Mariano from 2001 until his final guest appearance in 2006.

After his own WB series The Bedford Diaries, a recurring role as Meg Pryor's love interest on NBC's American Dreams, and playing Rocky Balboa's son in the sixth and final installment of the Rocky series, Rocky Balboa, Ventimiglia's big break came in 2006 when he received the part of nurse-turned-superhero Peter Petrelli for four seasons on NBC's Heroes.

Ventimiglia was born in Orange County, California, the son of Carol (née Wilson) and Peter Ventimiglia. His father is of Sicilian descent and his mother has English, Irish, Scottish, French, and Cherokee Native American ancestry. His last name, Ventimiglia, is the name of the town of Ventimiglia in Liguria, Italy, which later gave its name to another city, Ventimiglia di Sicilia. The youngest of three children, he has two older sisters, Leslie and Laurel. He has explained in an interview with USA Today that his "crooked mouth" is a result of dead nerves on the left side, which cause that side to remain immobile, much like, incidentally, Sylvester Stallone, with whom he worked in Rocky Balboa.
