In 2013, the film Philomena based on the book The Lost Child of Philomena Lee, opened in cinemas worldwide. It tells the true story of Philomena's 50-year-long search for her forcefully adopted Irish infant son, who was sent to the United States. She is eventually assisted by BBC journalist Martin Sixsmith, which takes up the majority of the film. Starring Judi Dench as Philomena and Steve Coogan as Sixsmith, it was nominated for four American and four British Academy Awards.
Open adoption has slowly become more common since research in the 1970s suggested that open adoption was better for children. In 1975 the tide began to change, and by the early 1990s open adoptions were offered by a majority of American adoption agencies. Especially rapid progress was seen in the late 1980s and early 1990s - between 1987 and 1989 a study found only a third of agencies offered fully open adoption as an option; by 1993 76 percent of the surveyed agencies offered fully open adoptions. As of 2013, roughly half of US states consider them legally binding, however contact in open adoption is not always maintained.
Adoptive parents may be less likely to consider the possibility that they are doing something wrong, and blame the child's heredity. The parents may even unfavorably compare their adopted child with a near-perfect, genetically-related "fantasy" child. This enables them to blame ordinary problems which all parents face on their child's supposedly "defective" genes. Thus, while non-adoptive parents are focused on nurture, some adoptive parents are solely focused on nature (i.e. heredity) instead. This results in what could have been an easily resolved problem, going unresolved in families with adopted children, possibly accompanied by child abuse.
There are also private search companies and investigators who charge fees to do a search for or assist adoptees and birth mothers and fathers locate each other, as well as to help other types of people searching. These services typically cost much more, but like search organizations and search angels, have far greater flexibility in regards to releasing information, and typically provide their own intermediary services. However, they may not circumvent the law regarding the confidentiality process.
