The correct answer is:<em> Veamos una película.</em>
Explanation:
In Spanish there isn’t a direct translation for the use of the word “<em>Let’s</em>” as used in this sentence to express a command or a suggestion. Rather, in Spanish language,<em> the verb is conjugated in its imperative form and then it’s followed by the direct complement</em> (“<em>una pelicula</em>”).
<em>In this case the verb watch is translated to the verb “ver” and then conjugated to the imperative form for the first person of the plural (“nosotros”). </em>
<em>Note</em>: When translating directly from English it isn’t clear that the command is directed to a “<em>we</em>” form (“<em>nosotros</em>”). Nevertheless, this translation uses the “<em>nosotros</em>” pronoun because using other personal pronoun might not be as accurate.
