Dean Martin's daughter is still searching for the perfect actor to portray the late singer/actor in a new biopic, two years after announcing plans for the project.

Deana Martin's memoir, Memories Are Made of This, is set to be turned into a movie, which will be directed by The Godfather: Part Iii star Joe Mantegna, and she has recruited Jennifer Love Hewitt to play herself in the film - but the singer has yet to find her movie dad.

Martin previously stated in 2012 that Johnny Depp was at the top of her wish list to play the Rat Pack icon on the big screen, but the character's casting is still undecided.

She says, "It has to be the perfect person who can portray all the qualities of my dad. It's a big role to fill and, as of yet, I haven't found that person."

Martin hopes to find the right actor to take on the role so production on the project can begin later this year (14).
