A postscript (P.S.) is an afterthought, thought of occurring after the letter has been written and signed. The term comes from the Latin post scriptum, an expression meaning "written after" (which may be interpreted in the sense of "that which comes after the writing").
A postscript may be a sentence, a paragraph, or occasionally many paragraphs added to, often hastily and incidentally, after the signature of a letter or (sometimes) the main body of an essay or book. In a book or essay, a more carefully composed addition (e.g., for a second edition) is called an afterword. The word "postscript" has, poetically, been used to refer to any sort of addendum to some main work, even if it is not attached to a main work, as in Søren Kierkegaard's book titled Concluding Unscientific Postscript. Sometimes, when additional points are made after the first postscript, abbreviations such as PSS (post-super-scriptum), PPS (postquam-post-scriptum) and PPPS (post-post-post-scriptum, and so on, ad infinitum) are used, though only PPS has somewhat common usage.
p.s. is a 2004 drama film directed by Dylan Kidd. The screenplay by Kidd and Helen Schulman is based on Schulman's 2001 novel p.s. The film stars Laura Linney and Topher Grace.
Thirty-nine-year old divorcée Louise Harrington (Linney) works in the admissions office at Columbia University School of the Arts. She is unnerved when she receives an application from F. Scott Feinstadt (Grace), the same name of her high school sweetheart who was killed in a car crash, and calls the student to arrange an interview. His appearance, mannerisms, and painting style closely resemble those of her former love, and she begins to suspect the young artist may be the reincarnation of her old flame. Hours after meeting, the two embark upon an affair. Also complicating Louise's life are her relationship with her ex-husband Peter (Gabriel Byrne), who confesses he is learning to cope with a sex addiction that, unknown to her, plagued their marriage; her ne'er-do-well brother Sammy (Paul Rudd), who is favored by their mother Ellie (Lois Smith) despite his shortcomings; and her best friend Missy (Marcia Gay Harden), who stole the original Scott from Louise before his death and seems intent on doing the same with the contemporary version.
"P.S." is a mini episode of the seventh series of Doctor Who, written by Chris Chibnall. Set after the departure of Amy Pond and Rory Williams in "The Angels Take Manhattan", it depicts a letter that Rory sent to his father Brian explaining why he and Amy are not returning. This episode was dubbed "the scene that was never shot", as it was released in complete storyboard drawings.
The final scene from "The Power of Three" is shown, before the titles.
Afterwards, in complete drawing format, Brian is shown watering the plants, when there is a knock at the door. A man, Anthony, from New York, hands Brian a letter. Anthony tells Brian that he'll wait indoors until he has read it.
Brian sits down and reads the letter, which is from his son Rory. It explains that Brian will never be able to see him or Amy again, and he apologises. Rory also explains that the person who delivered the letter is Brian's grandson, Anthony Brian Williams, whom Amy and Rory adopted in 1946.
After Brian reads the letter, he walks out to Anthony, who offers a handshake. The two then embrace in a hug as the episode closes.
