O.J. Simpson – charged with killing his wife Nicole Brown Simpson and her friend Ronald Goldman – was freed more than 15 months after police infamously chased his white Bronco across Orange County expressways.

Now, as the country looks back in a trial that eternally influenced the news cycle, the national race conversation and also the understanding of a Pro Football Hall of Fame inductee, rarely seen footage of O.J. Simpson testimony will resurface on ABC News’ “20/20” Saturday night at 10 p.m. ET – and will reveal several instances of controversial, cryptic testimony.

The tapes actually come from an alternate trial; Simpson never testified in 1995.

When the families of Nicole Brown Simpson and Ronald Goldman filed a wrongful death civil suit, Simpson took the stand.

It’s t, ABC reveals, that Simpson confessed to physically injuring his wife in a weird back and forth with lawyer Daniel Petrocelli.

Simpson’s fall from grace came abruptly after an illustrious football career propelled him to pop culture superstardom and acting success.

The 1968 Heisman Trophy-winning running back out of USC went to rush for more than 11,000 yards in the NFL. Most of those yards came during Simpson’s tenure with all the Buffalo Bills, w he notoriously eclipsed 2,000 yards rushing in 1973 on his way to winning league MVP. Simpson – inducted into Canton’s Pro Football Hall of Fame in 1985 – was a five-time first-team All-Professional and sits at No. 19 among all time rushing yard leaders.
