Is it true that were the olsen twins in the flintstones movie based on the following text?

The Flintstones is a 1994 American buddy comedy film directed by Brian Levant and written by Tom S. Parker, Jim Jennewein, and Steven E. de Souza. It is a live-action adaptation of the 1960-66 animated television series of the same name. The film stars John Goodman as Fred Flintstone, Rick Moranis as Barney Rubble, Elizabeth Perkins as Wilma Flintstone, and Rosie O'Donnell as Betty Rubble, along with Kyle MacLachlan as a villainous executive-vice president of Fred's company, Halle Berry as his seductive secretary (named after a famous actress), and Elizabeth Taylor (in her final theatrical film appearance), as Pearl Slaghoople, Wilma's mother. The B-52's (as The BC-52's in the film) performed their version of the cartoon's theme song.
