Pixar ( PIXR) shares jumped Monday following a successful weekend for its movie Finding Nemo.

The computer-animated movie raked in an estimated $70.6 million in ticket sales over the weekend, a record for an animated picture, according to media reports.

A co-production with Walt Disney ( DIS), Pixar's movie sold about twice as many tickets as its No. 2 rival, Jim Carrey's Bruce Almighty.

After each debut of their four co-productions, Pixar and Disney have hit the No. 1 spot on the weekend box office charts, and their shares have surged. But analysts noted that investors eventually had sent the stocks back to previous levels on each occasion.

Other companies are poised to bank some profits from the movie's expected popularity among kids. McDonald's ( MCD) will soon introduce its Happy Meals with Nemo characters; Hasbro ( HAS) is rolling out Nemo toys; PepsiCo's ( PEP) Frito-Lay will come out with a trip to Australia, the underwater setting for the film; and Kellogg ( K) will make cereal promotions with the Nemo theme.

Shares of Pixar were up $1.78, or 3.15%, at $58.33 around midday, while Disney shares were up 36 cents, or 1.8%, at $20.01.
