'Transformers' Star Shia LaBeouf Might Play Indiana Jones' Son

'I would love to, but it's a rumor now,' is all actor will say.

If adventure has a name, it must be ... Shia LaBeouf?

The 20-year-old "Transformers" star is in final negotiations to play the son of Indiana Jones (Harrison Ford) in Steven Spielberg's still-untitled "Indiana Jones 4," Variety reported (see "George Lucas Says Indiana Jones Will Return In May 2008").

Reached for comment on Thursday evening, LaBeouf declined to confirm the report to MTV News, saying only, "It's a fun rumor. That's exactly what it is. I would love to, but it's a rumor now." Representatives for Paramount Studios had not responded to requests for confirmation by press time.

Written by screenwriter David Koepp, "Indiana Jones 4" is set to once again follow the intrepid adventurer as he scours the globe searching for an object of immense value, producer George Lucas hinted in an interview with U.K. film magazine Empire.

But for fans of the series, LaBeouf's involvement raises more questions than it does answers — namely, who is his character's mother? Based solely on appearance, Internet speculation pegs former Indy flame Marion Ravenwood (Karen Allen) from "Raiders of the Lost Ark" as the mom. That story line would also tie in nicely with the series, since Marion's father, Abner, was indicated to be a mentor and father figure to Dr. Jones.

It is also unclear how LaBeouf's role works into what we've learned from past Jones material. In TV's "The Young Indiana Jones Chronicles," an elderly Indiana (played by George Hall) was shown living in New York City with his daughter and several grandchildren. No mention was ever made of Indiana having a son.

Set for release over next year's Memorial Day weekend, "Indiana Jones 4" will start filming this June, though precious few tidbits about the story line have been revealed so far. For instance, while LaBeouf's real age would seem to indicate that audiences will be seeing a much older Indiana, it is unclear whether the long lag time between sequels ("The Last Crusade" was released in 1989) will be reflected in the flick's plot.

No word has been released on other possible castmembers, although Sean Connery, as the popular Henry Jones Sr., is expected to be offered a role.
