Real Life with Jane Pauley was a newsmagazine television program aired in the United States by NBC from 1990 to 1991.
 "Real Life with Jane Pauley" seemed to be presented as an answer to both critics and members of the general public to the frequently-repeated viewpoint that "television news never seems to show anything positive".
 "Real Life" focused on positive, human interest-type stories and occasional celebrity profiles.
 Jane Pauley also presented less uplifting but still-lightweight features as well, such as a feature focusing on how less than 20% of the people who owned VCRs at the time actually knew how to program them.
 Boyd Matson was also featured as a correspondent; his reports featured stories on out of the way places.
John Guilbert Avildsen (December 21, 1935 – June 16, 2017) was an American film director.
 He won the Academy Award for Best Director in 1977 for "Rocky".

Tommy David Morrison (January 2, 1969 – September 1, 2013) was an American professional boxer who competed from 1988 to 1996, and held the WBO heavyweight title in 1993.
 He retired from boxing in 1996 when he tested positive for HIV, but returned for two more fights in 2007 and 2008.
 Morrison is also known for starring alongside Sylvester Stallone in the 1990 film "Rocky V".
This is a list of characters from the "Rocky" film series, consisting of "Rocky" (1976), "Rocky II" (1979), "Rocky III" (1982), "Rocky IV" (1985), "Rocky V" (1990), "Rocky Balboa" (2006), and "Creed" (2015).
An interrogation scene is a form of BDSM roleplay in which the participants act out the parts of torturer and victim.
 As in real life torture chambers throughout the world over, the "torturer" uses threats, humiliation and physical pain to extract whatever information he/she believes the "victim" possesses.
 The game is over when the victim has broken and divulged the secret.
 The length and severity of the scene will vary according to the temperament of the players.
 Dedicated players attempt to replicate the atmosphere of a real torture session and, as in real life, the "victim" can expect to be stripped naked, tied up, mocked and abused.
Rocky V is a 1990 American sports drama film.
 It is the fifth film in the "Rocky" series, written by and starring Sylvester Stallone, and co-starring Talia Shire, Stallone's real-life son Sage, and real-life boxer Tommy Morrison, with Morrison in the role of Tommy Gunn, a talented yet raw boxer.
 Sage played Robert Balboa, whose relationship with his famous father is explored.
 After Stallone directed the second through fourth films in the series, "Rocky V" saw the return of John G. Avildsen, whose direction of "Rocky" won him an Academy Award for Best Directing.
