Some context: Dorothy Jane Roberts (May 8, 1929 - September 5, 1984) was an American author, poet, self-proclaimed psychic, and spirit medium, who claimed to channel an energy personality who called himself "Seth." Her publication of the Seth texts, known as the Seth Material, established her as one of the preeminent figures in the world of paranormal phenomena. The Yale University Library Manuscripts and Archives maintains a collection entitled Jane Roberts Papers (MS 1090), which documents the career and personal life of Jane Roberts, including journals, poetry, correspondence, audio and video recordings, and other materials donated after her death by Roberts' husband and other individuals and organizations.
Seth's effect upon New Age thinkers has been profound. The title jacket of "The Nature of Personal Reality, A Seth Book," published in 1994 (Amber-Allen/New World Library), contains testimonials from some of the most notable thinkers and writers within the movement. Marianne Williamson, Deepak Chopra, Shakti Gawain, Dan Millman, Louise Hay, Richard Bach, and others express the effect the Seth Material had upon their own awakening. In words similar to Williamson's they state: "Seth was one of my first metaphysical teachers. He remains a constant source of knowledge and inspiration in my life." Catherine L. Albanese, professor of religious history at the University of Chicago, stated that in the 1970s the Seth Material "launched an era of nationwide awareness" of the channeling trend. She believes it contributed to the "self-identity of an emergent New Age movement and also augment[ed] its ranks."  John P. Newport, in his study of the impact of New Age beliefs on contemporary culture, described the central focus of the Seth material as the idea that, for each individual: "you create your own reality." (Briefly summarized, our beliefs generate emotions which trigger our memories and organize our associations. Eventually those beliefs become manifested in our physical lives and health.) Newport wrote that this foundational concept of the New Age movement was first developed in the "Seth Material." Historian Robert C. Fuller, a professor of religious studies at Bradley University, wrote that Seth filled the role of guide for what Fuller called "unchurched American spirituality," related to concepts of reincarnation, karma, free will, ancient metaphysical wisdom, and "Christ consciousness."  Some writers noted, "Husband Robert Butts stated that similarities exist between Seth's ideas and those of various religious, philosophical, and mystical doctrines from the Near, Middle, or Far East... and we've done a little reading on Buddhism, Hinduism, Zen, and Taoism, for example, not to mention subjects like shamanism, voodooism, and obeah."  The late amateur physicist Michael Talbot wrote, "To my great surprise--and slight annoyance--I found that Seth eloquently and lucidly articulated a view of reality that I had arrived at only after great effort and an extensive study of both paranormal phenomena and quantum physics."

Some context: For the theatre adaptation, see Shakespeare in Love (play). Shakespeare in Love is a 1998 American romantic period comedy-drama film directed by John Madden, written by Marc Norman and playwright Tom Stoppard. The film depicts an imaginary love affair involving Viola de Lesseps (Gwyneth Paltrow) and playwright William Shakespeare (Joseph Fiennes) while he was writing Romeo and Juliet. Several characters are based on historical figures, and many of the characters, lines, and plot devices allude to Shakespeare's plays.
After the film's release, certain publications, including Private Eye, noted strong similarities between the film and the 1941 novel No Bed for Bacon, by Caryl Brahms and S. J. Simon, which also features Shakespeare falling in love and finding inspiration for his later plays. In a foreword to a subsequent edition of No Bed for Bacon (which traded on the association by declaring itself "A Story of Shakespeare and Lady Viola in Love") Ned Sherrin, Private Eye insider and former writing partner of Brahms', confirmed that he had lent a copy of the novel to Stoppard after he joined the writing team, but that the basic plot of the film had been independently developed by Marc Norman, who was unaware of the earlier work.  The film's plot can claim a tradition in fiction reaching back to Alexandre Duval's "Shakespeare amoureux ou la Piece a l'Etude" (1804), in which Shakespeare falls in love with an actress who is playing Richard III.  The writers of Shakespeare in Love were sued in 1999 by bestselling author Faye Kellerman. She claimed that the plotline was stolen from her 1989 novel The Quality of Mercy, in which Shakespeare romances a Jewish woman who dresses as a man, and attempts to solve a murder. Miramax Films spokesman Andrew Stengel derided the claim, filed in the US District Court six days before the 1999 Academy Awards, as "absurd", and argued that the timing "suggests a publicity stunt". An out-of-court settlement was reached but the sum agreed between the parties indicates that the claim was "unwarranted".
