AUSTIN (CBSFDW.COM/AP) — Filmmaker Richard Linklater is the latest celebrity wading into the tight U.S. Senate race in Texas with a social media ad attacking Republican Sen. Ted Cruz.

Best known for writing and directing “Dazed and Confused,” the coming-of-age comedy that followed a group of Austin teenagers, Linklater made a 30-second spot for a political action committee backed by Cruz opponents. It doesn’t mention Democratic Congressman Beto O’Rourke, who has campaigned on rejecting outside groups’ money but can’t control their actions.

The ad revives a character from Linklater’s 2011 film “Bernie,” who mocks Cruz for embracing President Donald Trump after the billionaire insulted his family during the 2016 presidential campaign.

During a debate in September, Cruz said he put aside personal feelings after the election to do his job.

Country music legend Willie Nelson held a concert for O’Rourke last month in Austin.
