Randy Quaid, a once-acclaimed actor who fell from grace nearly a decade and a half ago due to his eccentric conduct and legal troubles, is rumored to be plotting a return to the limelight, Entertainment Times has learned.

The older sibling of renowned actor Dennis Quaid has led an isolated existence in recent years with his wife, Evi. However, last month saw Quaid, 72, re-emerge at a Dallas fan convention, sharing laughs with former "National Lampoon's Vacation" co-stars Chevy Chase and Christie Brinkley while signing autographs for a fee.

"Randy can be quite a handful, but movie enthusiasts still hold him in high regard," an insider revealed. "His appearance at the convention seems like an attempt to show he can re-integrate into the public sphere."

Best known for his boisterous portrayal of Cousin Eddie in the hit "Vacation" comedy series, Quaid also starred in several blockbuster hits, including "Independence Day." However, in 2008, his career abruptly hit a roadblock.

GLOBE has previously documented Quaid's fall from grace. He was banished permanently from the Actors’ Equity and fined $81,000 for alleged physical and verbal harassment of his "Lone Star Love" co-stars, allegations he refuted. The ensuing years saw him and Evi, 59, embroiled in more controversies, including a dispute over a hefty hotel bill and charges of squatting in a house they formerly owned. The pair eventually absconded to Canada, claiming they were fleeing for their lives from the U.S., but were returned to the States after five years.

Quaid, now a prominent right-wing activist, has resided in Vermont with Evi for the past 33 years, following a court's refusal to extradite them to California. A source revealed that Quaid, who has only filmed one movie since 2009, is desperately seeking a financial lifeline.

"The truth is, Randy and Evi are in dire need of cash flow. He earns a fee for appearances at these fan events," a source shared.

"Despite having soured numerous relationships in Hollywood, Randy is on the hunt for new acting opportunities. He's keen to prove he can be a team player once more.

"Rumour has it he's even contemplating reaching out to his brother Dennis for support, despite the fact they haven't communicated in over two decades," the source concluded.

GLOBE reported on the sources' comments.
