According to Nola.com, there is no word yet from Universal Pictures, the studio behind the big-budget project "Jurassic Park 4" on Ron Howard's confirmation of Chris Pratt's involvement in "Jurassic World".

According to Production Weekly, the film start date for "Jurassic World" has changed to June 2nd, 2014 in Louisiana. Initially, "Jurassic Park 4" was said to start filming earlier in the year in Hawaii, but it looks like the Hawaii shoot might take place later on instead.
